Whenever you wanna add a coating line, this machine should be a major choice in your hand.

Machine details

a) Nuts Input Subsystem:

 (Note: The word "nuts" is used as in the description. However besides nuts or peanuts, it is also able to handle sunflower seeds, broad beans and green peas). The nuts input subsystem consists of an upper tank and lower tank. Upper tank may store up to 150KG of nuts, ready to be dispensed to lower tank. The lower tank stores the exact amount of nuts for each batch of coating. The amount of nuts  for each batch (e.g 4-5KG per batch) can be defined and store in the PLC system. The lower tank sits on a weighing system. When the weight of content in the lower tank reaches the  defined weight (for each batch) set in the PLC, the door at the upper tank will shut, stopping dispensing of nuts to lower tank. The door at the upper tank is controlled by the PLC.

The nuts input subsystem may be operated under 2 modes:






This is the default mode. Under this mode, the upper tank stops dispensing after the weight of the lower tank reaches a defined setting (this is defined under Appendix I: Parameter Page).



This mode is selected if the physical weigher is faulty. In this mode, upper tank will stop dispensing after a defined timing. Note the modes will need to be manually selected at the Parameter Page.

b) Flour Input Subsystem

The flour input subsystem consists of a flour tank, flour press and flour applicator. The flour tank may store up to 60KG of flour. The flour press consists of a motor and screw blades to push the flour into the flour applicator. Flour is fed to the coating pan via the flour applicator. The flour applicator consists of a conveying screw, motor and servo. The speed of the screw is controlled by the motor and servo. The servo is controlled by the PLC. The frequency of flour feeding to flour applicator and the speed of the screw in flour applicator can all be defined at the Parameter Page


c) Syrup Dispenser Subsystem


The syrup dispenser subsystem consists of a syrup container, pump and dispensing pipe. The syrup container can store up to 30KG of liquid. Syrup is pumped to the coating pan via a pump, through the dispensing pipe. The dispensed syrup is targeted onto a rotating disc at the base of the coating pan. When coating starts, the syrup hits on the rotating disc and sprinkles to the nuts that are spinning at the wall of the pan. The flow of dispensed liquid can be defined at the Parameter Page.   

d) Sprinkler


The sprinkler consists of a rotating disc at the base of the coating pan and a motor/servo controlled by the PIC. The disc is rotated by a motor that is controlled by the PIC. During coating when syrup is dispensed onto the disc, the syrup will sprinkle to the spinning nuts. The rotating speed of disc can be defined at the Parameter Page.

e) Coating Pan Subsystem


The coating pan subsystem consists of a high speed rotating base plate and stationary pan structure. The coating process requires the base plate to rotate at high speed, causing the nuts to spin at the wall of the stationary pan. When flour and syrup are dispensed, the rotating nuts will be coated. The wall of stationary pan is designed with angular edges to improve the coating. The speed of the rotating base plate can be defined at Parameter Page.

 f) PLC

The operation of the machine is controlled by a PLC. The machine can by operated by either automatic or manual mode.






This is a recommended mode of operation. Parameters need to be pre-set in Parameter Page. Operator may then run the machine by activating "Run"/"Stop" buttons at Automatic Operation Page . 



This mode is typically used during testing and calibration


How is the most popular coated peanut made?


Koh-Kae is the first nut snack brand in Thailand which was found in 1964. The first products were fried peanut crackers and shrimp rice crackers. In 1976, they produced the Coconut cream flavour coated peanuts. They keep on doing research and developing new flavours and products to fulfil the customers’ satisfaction. Since then, Koh-Kae became everyone favourite peanut snacks because of the tastiness and crunchiness. Koh-Kae peanut snacks are not just tasty and crunchy but they are also a healthy choice for consumers.(source:asiaexpressfood)


At present, the world and most of the domestic nut manufacturers are using l semi-automatic coating machine.  

The characteristics of manual or semi-automatic coating machine are as follows:  

1. First of all, in terms of manpower and material resources, the factory has a large input, workers need continuous operation, and the stability of products is uncertain.  

2. Material is also relatively large investment, due to the uneven coating process, it is easy to appear multiple births, or the phenomenon of powder pellets, cleaning and screening also add a process, making production more difficult and labor costs increase.  

3. Moreover, in terms of safety, manual operation is basically a number of mechanical repetitive movements, workers need to constantly move, lift, put, scatter, move and so on.  

4. In the traditional way of coating powder, dust fills the space. Even if you wear a mask and hat, you are covered with dust all over.  If you work for a long time, you may suffer from physical diseases.  

5. From the perspective of nutrition, the coating products coated in the traditional way are uneven in powder, thickness and tightness.  The taste is not good.  Fried products in particular need a longer time to fry, nutrients in the frying process loss or deterioration.


Handyware Engineering has a whole series of auto coating machine for this coated peanuts.It is suitable for coating of peanuts, sunflower seeds, green peas and other nuts. Manufacturers switching from traditional manual coating to use of Automatic Coating Machine would see product quality improvement and long term cost savings.

The reasons of coated peanuts, corn chips and pellet chips cannot share fryer

1.Coated peanuts require a much longer frying time compared to pellets. Coated peanuts frying time is 5-6 mins while pellets are typically 10-12 sec. Hence coated peanuts fryer is typically much longer than pellets fryer.

2. The thermal transfer requirement for coated peanuts, corn chips and pellets are very different. To share the same burner specification for these products will result in oil getting rancid for certain product, as the thermal transfer requirement are different.


3.The shapes of coated peanuts, corn chips and pellets are different. The paddles design will be different.
4.Coated peanuts fryer requirement for fines removal is much higher than pellet fryer.  

How Ecommerce Is Energizing China Nuts Snacks Industry

In 2012, Mr Zhang Xian Yuan, founder of the now one of the biggest China Ecommerce food snacks brand Three Squirrels, mentioned that a new e-commerce era is coming. There is a five-year opportunity for e-commerce (food snacks) in China. Within five years, you can become an Internet e-commerce brand. After five years, it will definitely be the beginning of its demise. .


In the past 8 years, the nuts snacks industry in China has seem an exponential growth, due the enormous success of Ecommerce platform such as Taobao, JinDong etc. Ecommerce brands such as Three Squirrels, Liang Ping Pu Zhi, Bai Chao Wei pushes product to the 1.3 billion population domestic market. Leveraging on the various shopping culture festive dates such as the famous “double 11”, ecommerce brands sales growth reaches unprecedented level. Taking Three Squirrels for example, in a short pan of less than 10 years, it has grown into a 10 billion yuan company


In the midst of the very difficult past 18 months due to Covid 19, one bright light appears to be online shopping of food snacks. This further drives ecommerce sales.  


Driven by the ecommerce success, nuts product has been one of the fastest growing snacks in China. As the Chinese population becomes more affluent, customers are looking for more health-conscious choices when selecting snacks. Nuts being rich in protein and minerals are becoming very popular snack option.


Coated nuts in particular, has been very hot among consumers. Coated nuts in the market included multi-flavor coated peanuts, salted egg seeds, coated cashews, beef seasoning coated broad beans, half coated green peas, fish skinned peanuts (Japanese peanuts) etc



The coated nuts manufacturers have then seen a rather happy problem. Despite the need to cater to the multi-billion yuan market demand, majority of the manufacturers till 2019, are still using labour intensive method to coat nuts. The “big drum” labour intensive machine has been the mainstream coating machine used since coated nuts first appeared in China in the 1990’s. The machine will require a labour to stand in front of a big rotating drum, manual add nuts, flour and syrup into the drum to perform coating. Besides labour intensive, the process is unstable (inconsistent coat among labours), unclean (flour all over the factory), unhealthy to the labour (inhale dust particles in the air) and extremely exhausting for the labour.  


Handyware Engineering has developed an Auto Coating Machine that addresses the above-mentioned issues. It has high output, labour-saving, clean, and improve product stability. It is versatile and can coat peanuts, seeds, broad beans, peas and cashew nuts.


Handyware Engineering is a market leading expert in nuts coating automation. It has delivered solutions to more that 30 OEM manufacturers of the ecommerce giants such as Three Squirrels, Liang Ping Pu Zhi, Bai Chao Wei, and has customers from India (Haldiram’s), Indonesia (PT Dua Kelinci), UK (AIB Foods) and many more.

Benefits of Using Handyware Automatic Coating Machine

Since at early 1980’s, Japanese snacks manufacturers had created the Japanese peanuts snacks. In the 1990’s, such snack slowly gained popularity. The coating machine used was very simple but requires intensive labour involvement.


It involves having a labour manually pouring peanuts, flours and syrup into a rotating drum throughout every batch of coating.


As such snacks slowly gained popularity throughout Asia (China in particular has the biggest market), manufacturers adopted similar way in coating their product, It is simple and low in machine investment, but extremely labour intensive. The welfare of the labour (long term inhalation of dust particles) is also a concern.


This leads to a need for a lower labour intensive, and cleaner solution. The Handyware Automatic Coating Machine (or system) is designed to resolve the labour issue. Besides, it is a much cleaner solution, ensuring a much cleaner factory environment,



Handyware provides a full automatic solution of material handling, mixing, coating and even frying or roasting


Mixing is a very important stage of the entire process. The Handyware mixer homogeneously mix the raw material of flour, starch, sugar (and others). If the mixing is not well done, flow of material will not be uniform, resulting in bad coating


The coating process requires uniform application of syrup and flour mixture onto the peanuts. Handyware auto coating machine has special designed (patented) flour and syrup application solutions. Unlike manual (traditional) coating, the requirement for flow of material in machine coating is much higher  


Note: Handyware achieved the following patents for the above Auto Coating Machine solution:

  • ZL 2019 2 1065333.7
  • ZL 2019 2 1065332.2
  • ZL 2019 2 1064472.8
