Puffed Food Lead machinery market
作者：xinuo 时间：2015/5/6 15:19:32 来源：互联网
When American Ward applied for the first patent on puffing in 1856, he must have never imagined that a century later the expansion technology would be applied to so many areas: plastic, feed, food, chemical, pharmaceutical, grease processing and so on; he would not have thought the extruder was developed from single screw to twin screw, and the twin-screw extruder would have the same rotating, non meshing relative rotation, meshing with the same direction rotation, meshing relative rotation so many forms. More and more people know the magic of extrusion, more and more food raw materials are inflated by extrusion.
Puffed food is one of the items. Extruded food with its delicious taste crisp, easy to carry edible, wide range of raw materials, taste changeable and other characteristics, increasingly become consumer favorite food, with the people's living standards continue to improve, it has become an important part of the food industry, and the market potential is enormous. The market demand of puffed food also led to the development of mechanical equipment.
Classification of Extruder
Because of the different use and equipment, puffed food has the following three types: one is the use of extruded extruder, corn and yam as raw materials for the production of small food; the second is the use of extruded extruder, plant protein as raw materials for the production of tissue-like protein food (plant meat); In addition to the production of indirect heating extruder, a variety of puffed food was produced by using extruded powder of refined grain.
Current situation of extruder
In the past 20 years, domestic screw extruder is represented by a single screw extruder in some domestic companies, although the performance of a single, processing capacity is not high, but with its low price, but also in the United States Wenger, Switzerland Buhler, France Clextra and other internationally renowned enterprises produced twin screw extruder Eminence domestic market. After all, insiders know that the twin-screw extruder in the quality control and processing flexibility has an irreplaceable advantage; they are more aware that the twin-screw extruder is extremely demanding in terms of material, pitch, helix angle, root diameter, torque and blade cross-section, as well as the precision of the fabricated block-type segmented spiral.

Expansion machine also needs to adapt to the market
(1) Scale applicability. The equipment used in Chinese puffed food processing enterprises is mainly divided into big, medium and small three kinds. According to the National Industrial policy and industry development requirements focus on the development of large-scale production scale, and small-scale production enterprises should be in accordance with market economy rules to fend for themselves. However, China's puffed food machinery manufacturing equipment mainly in equipment, small enterprises, and the use of large-scale equipment still has a large number of imports.
(2) Safety applicability. Safety applicability is the mechanical safety, production safety and food safety in puffed food processing. First, mechanical safety. is caused by the mechanical not to produce the effect of harm, reduce the mechanical risk to the minimum. Second, production safety. Sufficient safe production, industrial hygiene, to ensure the safety and health of workers in the production of the premise, from the management, production technology and equipment used to stipulate people's safety behavior and safety production requirements of the material conditions. Third, food safety. The dog food production equipment mainly includes the food hygiene, the food quality, the food nutrition and so on related aspect content.
(3) Complete set of applicability. Industrialized food processing, most of the lack of single machine production, but supporting the production line for the operation. Therefore, the complete set of applicability is to ensure continuous operation, balanced production, processing performance and product quality of the important link, its set of principles is to achieve a reasonable economic scale, meet the technical requirements of technology and equipment and the reasonable matching between the device, so that the normal operation of the production line, safety and health, energy saving and maintenance convenience, to ensure the production line of the advanced, reasonable and reliable
(4) Health applicability. It is the demand of the mechanical design and manufacture process of the extruded food on the mechanical structure, mainly includes the product contact surface and the non product contact surface structure material, the surface construction, the cleanliness, the durability, the inspection sex and so on the hygienic request; for the mechanical structure of food machinery, the key control points of health hazards should be determined and measures should be taken to ensure the hygienic requirements of the mechanical structure.
