Technical analysis of 35 type twin-screw puffing machine

In the fields of food processing and feed production, twin-screw puffing machines have gradually become indispensable key equipment due to their high efficiency and multifunctional characteristics. This article will provide a detailed analysis of the technical characteristics, working principles, performance advantages, and maintenance points of the 35 type twin-screw puffing machine, providing comprehensive technical references for practitioners in related industries.
1、 Equipment Overview
The 35 type twin-screw puffing machine is an advanced equipment that integrates heating, puffing, and molding, widely used in multiple industries such as food, feed, and chemical. Its main feature is the use of a twin-screw structure, which achieves material refinement, homogenization, and expansion through mechanical friction and shear under high temperature and pressure environments, significantly improving the quality and taste of the product.
2、 Working principle
1. Material transportation and heating
The material is first fed into the feed inlet of the extruder, and then flows axially under the rotation of the twin-screw. During this process, the material is subjected to mechanical friction between the screw and the barrel, as well as between materials, generating a large amount of heat. At the same time, direct steam can be introduced or indirect steam in the jacket can be used to heat the material as needed, gradually increasing the temperature of the material.
2. Refinement and homogenization
As the material is continuously squeezed, stirred, and sheared between the twin-screw, its particle structure is further refined and homogenized. In high temperature and high pressure environments, starch gelatinization, protein denaturation, and partial degradation of fibrous components in materials occur, while killing pathogenic bacteria and improving hygiene indicators.
3. Puffing and Forming
When the material is heated to a certain temperature and reaches an appropriate degree of softening, it rapidly expands, loses water, and cools down under the strong pressure difference when sprayed from the mold hole. The structure of the puffed product is loose, porous, crispy, and has good palatability and flavor. Meanwhile, by replacing molds of different specifications, various shapes and sizes of puffed products can be produced.
3、 Performance advantages
1. High efficiency and high quality
The twin-screw structure provides the machine with higher thrust and extrusion force, enabling better heating and puffing of materials. At the same time, the material is distributed more evenly in the machine, fully utilizing the heating and puffing effects, improving the overall quality and production efficiency of the product.
2. Flexible and versatile process adaptability
The 35 type twin-screw puffing machine can not only improve the feeding quality of various conventional materials, but also process a large amount of unconventional materials into high-quality feed or food materials. Wild plants, agricultural by-products, and livestock and poultry slaughter waste can all be processed and utilized through this equipment.
3. High temperature short-term sterilization and detoxification
During the puffing process, the material can reach a high temperature of 130-160 ℃, and the high temperature period is extremely short (about 5-10 seconds), effectively killing pathogenic bacteria and various harmful factors, improving the hygiene indicators and safety of the product.
4. Extend shelf life
High temperature treatment kills various microorganisms and insect eggs, inactivates various enzymes, eliminates various factors that cause material deterioration, and significantly extends the shelf life of the product.
4、 Key points of maintenance and upkeep
1. Maintenance of lubrication system
Regularly check whether each lubrication system has been filled with lubricating oil, and choose the appropriate lubricating oil for replacement according to local climate conditions. At the same time, ensure the reliable operation of the circulating cooling and cooling device to prevent equipment overheating and damage.
2. Electrical system maintenance
The electrical system should have good grounding protection devices and be maintained by professional technicians. Regularly inspect and clean components such as frequency converters and electrical fasteners to ensure the normal operation of the electrical system.
3. Equipment cleaning and inspection
After work every day, operators need to clean the equipment and environment, wipe off equipment stains, and clean residual materials inside the modulator. At the same time, regularly check the wear and tear of each component, replace vulnerable parts in a timely manner, and clean residual materials to prevent clumping, mold growth, or cross contamination.
4. Regular maintenance and overhaul
According to the equipment operation manual, conduct regular comprehensive and major maintenance on the equipment. Including replacing lubricating oil, cleaning spiral carbon deposits, checking the running in condition of bearings and gears inside the gearbox, etc. Ensure that the equipment operates in its optimal state and extend its service life.
conclusion
The 35 type twin-screw puffing machine plays an important role in the fields of food processing and feed production due to its high efficiency, flexibility, and safety. Through scientific and reasonable operation and maintenance, its performance advantages can be fully utilized, product quality and production efficiency can be improved, and greater economic benefits can be created for enterprises.
