Strain-measuring batch weigher
Application
The device is used for automated dosing of bulk food and no-food stuff, including non-free flowing ones, such as: chips, pasta, ravioli, flour, talk, mixes of dispersed herbs, etc.
Description
There are several versions of batch weigher, enabling fulfillment of a wide range of tasks. Each of them provides a customer with extensive opportunities at operation with a wide range of products in a wide range of doses.
Versions of batch weigher:
1. Standard
2. Chips
3. Light dose
4. Rigid container packing
5. Multihead version for mix production.
Standard
Standard version of the weigher is purposed for free-pouring products such as grits, sugar, sunflower seeds, nuts, small leaf tea, etc.
- range of dose adjustment is 5 to 1000g.
- max accuracy ± 1g.
Electronic module of the weigher has 12 adjustable characteristics, which enable most effective adjustment of operation modes, providing high rate of dosing accuracy and speed. The electronic module is also equipped with memory for up to 14 various settings. This enables quick transfer to packing of various products with various dose parameters.
For instance, observed parameters of one weigher channel are provided in table 1.

Chips
The chips modification is a result of many years’ experience with non-free flowing products such as chips, fried potatoes (straw), ravioli, crackers, large leaf tea, etc. The most effective processing of such products is provided with a set of specialized software with advanced features and storage bunker of special three-dimensional configuration, which enables the best mode of product weighing. This system also provides no-stop storage bunker discharge, which is essential for operation of coarse products. Test data of the weigher operation are provided in table 2.

Light dose
Light dose modification is designed for extra accurate light dosing of products. It enables weighing of 1-20g doses with max accuracy of ±0.1 g and up to 100 g doses with accuracy of ±0.4 g.
Such weighers can be operated with such products as spices (grinded and whole), small leaf tea, herbal tea, food and flavor additives, prefabricated mixes (jelly, etc.), dry coffee extract, sugar, dried cream, various pharmaceutical and veterinary preparations, including powdered ones, toxic chemicals and so on. Test data of light dose modification weigher operation are provided in table 3.

Each of the abovementioned modifications can be used both as a part of packing device, and as a part of conveyor packing line for filling of measured doses to ready rigid containers. They can also form multihead systems of several weighers of various modifications for preparation of multicomponent mixes with simultaneous filling to the intended containers.
Each modification can be derived into a device for semiautomatic packing of measured doses to ready containers.
