The role of screw weighing scales in the environmental protection industry

With the increasing awareness of environmental protection, various regions are gradually implementing garbage classification policies, one of which is food waste. Due to dietary habits, a large amount of kitchen waste is generated in daily life, including leftover food, vegetable leaves, fruit peels, eggshells, bones, etc. It mainly comes from home kitchens, restaurants, and other dining venues or food processing-related industries.

Food waste contains high levels of moisture and organic matter, making it prone to spoilage. Through proper treatment and processing, it can be converted into new resources. Waste with high organic content, after strict treatment, can be used as plant fertilizer, or to produce biogas for fuel and power generation. The oil component can be used to produce biofuels. As technology advances and environmental protection concepts improve, numerous food waste processing equipment and technologies have emerged to maximize the utilization of food waste and reduce its environmental pollution. Regardless of the processing method, the waste needs to be weighed before entering the processing flow. Screw weighing scales are required for the conveyance and weighing of food waste.

Due to the unique nature of food waste, there are more issues during the conveyance and weighing process compared to other pure, dry, powdered, granular, or small block-shaped materials. The main issues are as follows:

Issue 1: Food waste contains many impurities, causing equipment damage

Food waste contains many impurities such as vegetable leaves, fruit peels, eggshells, leftover food, and hard bones, which can easily cause material to stick to the blades, resulting in blockages and affecting the efficiency of conveyance and weighing. Poor classification and hard solids can also damage the blades of the screw feeder.

Issue 2: High moisture content in food waste

Food waste has a particularly high moisture content, often exceeding 80%, making it difficult to convey. If not handled properly, it can leak and cause secondary pollution. Additionally, due to the high moisture content, impact can occur when the material is fed into the inlet from the feed pump, resulting in inaccurate measurements.

Issue 3: Large volume of food waste conveyance

The large generation of food waste results in a large volume of conveyance and weighing, requiring the screw weighing scale to adapt to high weighing demands and maintain normal operation over time.

In response to the conveyance and weighing issues faced by environmental protection companies when processing food waste, Guo Nuo Xin Ke's screw weighing scales can provide customized solutions.

1. Axis-less screw weighing scale to solve the problem of entanglement and damage

For the issue of food waste wrapping around the central axis, an axis-less screw weighing scale can be used. This solves the problems of food waste wrapping around the blades, material adhesion to the blades, and debris damaging the blades, facilitating conveyance and accurate measurement without causing blockages.

2. 360-degree sealing to ensure no leakage, and unique flow stabilization technology

The screw weighing scale adopts a special 360-degree fully sealed structure to ensure that food waste does not leak. The axis-less screw weighing scale features an easy-to-clean spiral surface to ensure the hygiene of daily operations. It also employs unique flow stabilization technology to prevent material impact and blockages.

3. Customizable diameter sizes

The diameter of the screw weighing scale can be customized according to the volume of food waste to meet different conveyance demands.

Environmental protection is closely related to everyone. In daily life, garbage should be accurately classified for proper disposal. Guo Nuo Xin Ke's screw weighing scales play an important role in environmental protection, providing accurate conveyance and weighing of food waste to ensure smooth entry into the subsequent processing procedures, turning food waste into treasure.
