Glutinous Rice Ball Automatic Production Equipment Designed to Solve Problem of Extruding Dry Filling

The client sells a great variety of foods. Although glutinous rice ball was not one of the main products, he needed a solution to produce glutinous rice balls effectively. Therefore, he visited ANKO's booth at a Hong Kong exhibition. Compared to other glutinous rice balls, the client's filling recipe contains more ingredients, including peanut powder, coconut powder, and sugar powder, which makes workers hard to fill the same ingredient quantities into each glutinous rice ball. Nevertheless, it is also difficult for machine to extrude powder filling because it easily tends to clump up and clog the filling system. Therefore, for making stuffed food with powder filling, ANKO's Automatic Encrusting and Forming Machine with a special designed powder filling system is highly recommended.

Food Culture

Glutinous rice ball/cake is consumed in some Asian country. It is known as mochi in Japan and Taiwan and called nuomici in Hong Kong. Mochi is one of popular foods in Japan. The Japanese even have many ways to cook and eat mochi. For example, toast mochi and serve it with condensed milk or other kinds of sauce. In Taiwan, except the Hakka style mochi that is coated with peanut powder, various fillings can be wrapped into mochi to create different flavors and texture. And about nuomici, it is similar to mochi, but nuomici contains more moisture than mochi. In Hong Kong, nuomici is usually filled with the mixture of peanut and sugar powder, but sometimes people like plain ones. Hong Kong people like not only to have a nuomici at the end of a meal, but also to give a box of nuomici as a present.

Glutinous rice dough is very sticky. How to prevent the final products from sticking on the conveyor and deforming as being picked up?

When making glutinous rice balls, dusting a large amount of rice flour is required to prevent sticking, but the process is time-consuming. We suggested them using the SD-97W Automatic Encrusting and Forming Machine because it can be equipped with a turning round tray rather than a conveyor for producing sticky food. This tray with a thick layer of rice flour covered can prevent the final products from sticking and deforming as being picked up.

Food Equipment Introduction

  • Put mixed powder filling into the filling hopper
  • Put prepared glutinous rice dough into the dough hopper.
  • Extrude filling and glutinous dough into a cylinder.
  • Divide it into equal balls by the shutter unit.

The glutinous rice ball is made by SD-97W.

The SD-97W-made glutinous rice ball with thin wrapper and much filling.
The filling system is ingeniously devised to extrude powder filling such as peanut powder, coconut powder, powdered sugar, etc.

The filling system extrudes filling out with a "push" action. In general, filling which has flowability can be pushed out smoothly, powder in dry condition as well. However, when powder clumps up because of moisture, the filling system will be clogged by these clumps. Therefore, a stirring mechanism is designed to loosen clumped filling all the time.

Processing Line Planning

  • Sieving
  • Mixing
  • Rounding
  • Sealing

Automatic Encrusting and Forming Machine is designed to produce stuffed food products. The shutter unit divides stuffed dough into small or large products, from a minimum of 15 g to a maximum of 70 g. Patterned or non-patterned shutter unit is also optional to form different shapes of food such as baozi, coxinha, kubba, and the like.

Moreover, the multipurpose SD-97W features memory function to save five sets of parameter setting, which makes users avoid time-consuming correction and adjustment. In this case, the SD-97W for the client is equipped with a powder filling system, a non-patterned shutter unit and a turning round tray to collect sticky glutinous rice balls.

ANKO's SD-97 series Automatic Encrusting and Forming Machine extrudes dough tube and filling inside at the same time. Then, the stuffed dough tube is divided into small balls and collected by the turning round tray, which is covered with a layer of rice flour in order to prevent sticking as well as save labor and time. The production capacity of the SD-97SS shown in this video is around 1500-3600 pcs/hr. And the SD-97W can make about 2500-4200 pieces per hour.
