Many small and medium-sized food production business owners must weigh, fill and pack their products. Manual weighing results in wasted time and increased labor costs in the long run, limiting their production and business. An automatic weighing system is the best solution to this problem. And one of the most widely used weighing systems for granule packing machine is the multihead weigher.

Function

Filling

The multihead weigher can be used for filling granular materials. It can be filled into bags or into bottles. As the name suggests, the multihead weigher has multiple feeding ports, and each feeding port can be set with different weighing gram weights, thereby improving the filling accuracy. The highest precision can reach two decimal places. It is usually equipped with a vertical granule packaging machine and a granule doypack packaging machine.

Mixed Weighing

In addition to weighing a single material, the multihead weigher can also be used for weighing multiple materials simultaneously. It is necessary to select a special multihead weigher, divide the trough according to the type of mixed material, and then set different gram weight parameters to finally achieve the mix-material packaging effect.

Application

Different types of multihead weigher can be selected according to the characteristics of different materials. The following lists several common materials and the characteristics of the applicable multihead weigher.

Non-sticky, flowable Granule

Examples: mung beans, coffee beans, nuts, pet food

These materials are suitable for standard multihead weigher. The scale has a wide range of applications and can be used for weighing and filling of most granules. It has most of the advantages of multihead weigher, such as accurate dosing, individually adjustable amplitude and grammage for each hopper, etc.

Micro/Powder Granules

Example: sugar, salt, rice

To weigh such tiny particles, a leak-proof multihead weigher is necessary. Moreover, the accuracy requirements will be higher than the general-purpose type, and the error is controlled within the range of 0.5g.

Fragile Granules

Examples: potato chips, crackers, onion rings

The most significant requirement for all types of materials is shatter resistance. Therefore, the design of the electronic scale will minimize the drop height of the material. Hopper feeding uses sliding feed. Also, the inclination angle of the weighing bucket is gentle. It protects the integrity of the material in every way.

Sticky Granules

Example: mustard, pickled carrots

This type of material is of low fluidity and high viscosity. Therefore, it is particularly important to solve the sticky hopper phenomenon. First of all, the feeding method adopts twin-screw feeding to ensure accuracy. Second, the parts in contact with the material are all made of small patterned plates to increase the roughness and reduce the adhesion of viscous substances to the inner wall of the hopper. Third, the feeding port uses a scraper to cut the material, which effectively solves the sticking hopper phenomenon. Fourth, the inclination angle of the feeding chute is 60 degrees to ensure that the material falls smoothly.

Meat

Example: meat cubes, meat slices

Meat contains water and is prone to sticking. Therefore, the multihead weigher will switch to screw feeding, utilizing a rotating screw for feeding. At the same time, a drying and dewatering device is also equipped to effectively prevent the damage of electrical components caused by the humid environment.

Frozen Material

Example: dumplings, shrimp, seafood, ice cubes

Due to the high moisture content of quick-frozen foods, multihead weighers require strong water resistance. From the selected materials and configuration devices, waterproof and dry aspects will be considered.

Strip-shaped Material

Examples: egg rolls, finger biscuits, sausages

This kind of plastic unloading button is a slender chute, which can ensure that the material enters the packaging machine in a vertical state, and ensures that the packaging contents are placed neatly.
