Screw feeders are widely used conveying and measuring equipment in production. They can dynamically measure bulk materials during continuous conveying and complete quantitative feeding control based on measurement. They play a role in various industries. Screw feeders are suitable for materials of various characteristics, such as powdered, granular, and small block-shaped. Especially for powdered materials, screw feeders are more suitable than belt feeders.
In the feeding of powdered materials, the food industry is a common application area, such as for flour. The requirements for screw feeders in the food industry are also different. Understanding these requirements can help users in this situation to correctly and reasonably select equipment, accurately state their needs, and facilitate manufacturers to provide suitable equipment. The specific special requirements of powdered materials in the food industry for screw feeders can refer to the following points.
(1) Material and workmanship
Equipment used in the food industry must first meet its hygiene standards to ensure that materials are not contaminated during conveying. Therefore, screw feeders for conveying materials must meet the requirements of the food industry. The material should be stainless steel, and special processes should be adopted to ensure that the internal and external surfaces of the machine are smooth, free of burrs, and easy to clean and disinfect to ensure hygienic conditions. In addition, a smooth interior facilitates stable conveying and avoids material blockages.
(2) Design structure
Hygiene standards in the food industry apply not only to the interior of the conveyed material but also to the external environmental conditions. This requires that the material cannot be contaminated by the external environment during conveying. Furthermore, flour tends to fly up during conveying, causing material waste and affecting the production environment. Based on internal and external requirements, screw feeders used for conveying flour should adopt a unique sealed structure to prevent powdered materials from being exposed. This not only optimizes the external production environment but also prevents material spillage and avoids contamination of the material during conveying.
(3) Large conveying capacity
The conveying capacity of powdered materials in the food industry is not always high, but for materials with high demand such as flour, the conveying capacity is often large. Therefore, when selecting a screw feeder, the production capacity should be clarified first, and the conveying capacity, motor, and screw tube diameter of the screw feeder should be selected accordingly. Especially when conveying large amounts of materials, it is important to choose equipment with a suitable large conveying capacity.
(4) Flexible layout
The production environments for the application of powdered materials in the food industry vary. It is best to choose screw feeders that are flexible in layout, easy to install, occupy little space, and are simple to dismantle and move. These feeders have stronger adaptability and are more convenient to use in the later stages.
Screw feeders have specific requirements in different industries. The above are the key points that need special consideration for powdered materials in the food industry. Users can focus on whether the manufacturer meets their needs during the selection process. Guonuo Technology's screw feeders can be customized according to different industries and material characteristics, with different processes, materials, and design structures to meet various needs. Even for powdered materials in the food industry with stringent conditions, they can meet the requirements.
