Food puffing machine is a kind of equipment for processing puffed food. Food puffing machine has the characteristics of wide range of raw materials, flexible configuration, simple operation and various kinds of products. It is suitable for processing snacks, ready-to-eat cereals, dairy products, convenience foods and many other food production fields. Then the work of food puffing machine What is the principle?
By using the extrusion propulsion of unequal distance non-standard screw system of food extruding machinery, the material is filled rapidly while the gas in the material is discharged. The material is regurgitated by shearing force, which increases the pressure in the chamber. With the friction between the screw and the chamber, the material is fully mixed, extruded, heated, glued and pasted. Organizational change, mechanical energy is transformed into heat energy through friction of material in bore, which makes material become a cementitious state with fluidity. When material is extruded to outlet, the pressure changes from high pressure to normal pressure instantaneously. The original structure is destroyed, from high temperature to normal temperature instantaneously, so that numerous micro-porous structures are formed in it, resulting in rapid moisture content. The ground evaporates from the organizational structure and then expands through the cutting device.
Food extruding machine can change the shape of products by simply changing the mould, and produce products with different shapes and patterns. It has many kinds, uniform patterns and can form series products, which is conducive to the flexibility of production and marketing.
Main features:
1. Series of food extruding machines are mainly composed of feeding system, extrusion system, rotary cutting system, heating system, transmission system, lubrication system and control system.
2. The feeding system, driving system and rotary cutting system of extruder all adopt frequency conversion speed regulation, which has strong power and smooth operation.
3. Automatic lubrication and forced cooling to ensure the safe operation of the extruder.
4. For different raw materials, choose single screw feeding system, twin screw feeding system, uniform feeding, stable and reliable.
5. The screw is processed by special technology, wear-resisting, fatigue-resisting and long service life.
6. Different screw length-diameter ratio structure meets different process requirements.
Maintenance and Maintenance of Food Puffing Machinery
(1) Lubricating grease should be added to the box bearing in time. After 500 hours of operation, all lubricating grease should be replaced once. (Lubricating grease should be added properly before the new machine runs, and oil should be replaced after 200 hours of operation.)
(2) Other bearing parts should be regularly greased.
(3) Hard weight hammer is forbidden to be used in the disassembly and assembly of screw, screw sleeve and other vulnerable parts. Heavy weight or standing person are forbidden to be placed in the expansion chamber.
(5) Expanded raw materials should be cleaned up to prevent foreign bodies such as metals from entering the machine and damaging its parts.
_Food puffing machine inspects the quality of puffing machine at any time, and pays attention to replacing vulnerable parts.
(5) Keep the equipment clean.
_When the expanding material is not used or replaced after long-term shutdown, the material in the expanding cavity should be cleaned up to avoid caking, mildew or cross-contamination between the materials.
_As the wear of the vulnerable parts near the outlet is relatively fast, and the wear of the vulnerable parts near the inlet is less, when replacing the vulnerable parts, it should be replaced in turn from the outlet, and it is not suitable to replace many parts at one time.
