Automatic puffing equipment

Abstract

The invention provides automatic puffing equipment, and belongs to the technical field of food processing machinery. The automatic puffing equipment comprises a feeding mechanism, a preheating mechanism, a curing mechanism and a discharging mechanism, wherein the preheating mechanism and the curing mechanism are cascaded; the preheating mechanism comprises a first screw cylinder, a first screw rodand a first screw rod driving device; a first temperature and pressure monitoring device is arranged at an outlet of the first screw cylinder and is used for measuring the temperature and pressure ofmaterials at the outlet of the first screw cylinder in real time; the curing mechanism comprises a second screw cylinder, a second screw rod and a second screw rod driving device; and a second temperature and pressure monitoring device is arranged at an outlet of the second screw cylinder. Compared with a common single-cylinder puffing structure, the automatic puffing equipment provided by the invention adopts a two-stage single-screw-rod match puffing mode, is more beneficial to production parameter adjustment, stable in equipment operation and high in control precision, has relatively low energy consumption and an intensive volume structure, can meet the process requirements of food puffing in a segmented manner, and has relatively low equipment cost and relatively high production efficiency.

Description

technical field [0001] The invention relates to the technical field of food processing machinery, in particular to an automatic puffing device. Background technique [0002] The puffing machine is a kind of food processing machinery. The material is subjected to the heat energy converted from mechanical energy in the puffing machine, and the volume increases and puffs up. [0003] In the prior art, when the flour mixture is expanded into a type of food (including but not limited to spicy strips) for processing and expansion, the expansion machine is mainly in a single-tube structure. The barrel is heated and processed directly from the discharge port to form and expand. Such an extruder requires a long heating process from feeding to discharging, and the capacity of the extruder is low. In the prior art single barrel extruder technology, in order to improve the puffing efficiency, some will add extra heaters on the puffing machine barrel to improve the puffing efficiency co...

Problems solved by technology

In the prior art single barrel extruder technology, in order to improve the puffing efficiency, some will add extra heaters on the puffing machine barrel to improve the puffing efficiency control, and some will set two screws in the single barrel structure Even multiple screws are meshed and rotated. However, after the implementation of such a technology, the bulk of the extruder is often caused, the system transplantation performance is poor, and at the same time there are many unit structures, it is difficult to carry out effective parameter control or the parameter control is not uniform, and the puffing quality is poor.

Moreover, for enterprises, the additional functional units of the single-barrel extruder not only have high power consumption and are difficult to manufacture, but also the system units that cooperate with each other are more complicated, which is not conducive to small and medium-sized enterprises in terms of volume, structure or production capacity. cost considerations
