Technical Field

The invention relates to the technical field of food processing equipment, in particular to a constant-temperature puffing device.

Background

The screw puffing machine is a common device in food processing and has the function of puffing food through the extrusion effect of a screw. The main working principle of the screw puffing machine is that mechanical energy extruded by the screw is converted into heat energy, and the food is extruded and cooked by the heat energy generated when the screw rotates and is extruded. However, some temperature sensitive food materials, especially dry puffed food materials, are partially charred due to high temperature during extrusion in the screw puffing machine, and are partially cooked to an insufficient degree due to insufficient temperature, which greatly affects the quality of the finished product.

Disclosure of Invention

The invention aims to provide a constant-temperature puffing device which can keep a certain temperature in the food extruding and puffing process and prevent food from being coked due to overhigh temperature and insufficient curing degree due to overlow temperature.

The constant-temperature puffing device provided by the invention comprises a screw puffing machine, wherein a puffing screw is arranged in the screw puffing machine, and the key point is that a constant-temperature water jacket is sleeved on a shell of the screw puffing machine.

The constant-temperature water jacket is sleeved on the shell of the screw extruder, and food is fed forwards along the axial direction of the screw in the screw extruder by rolling extrusion, so that the food can exchange heat with the constant-temperature water jacket through heat conduction of the inner wall of the shell, a certain temperature range is ensured in the food extrusion and extrusion process, and the problems of food coking caused by overhigh temperature and insufficient cooking degree caused by overlow temperature can be prevented.

Furthermore, the constant temperature water jacket is integrally connected with the casing to ensure the constant temperature efficiency of the constant temperature water jacket.

Specifically, the screw bulking machine is a single-screw bulking machine or a double-screw bulking machine.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

In which the figures are as follows: 1. a screw bulking machine; 11. a housing; 2. a bulking screw; 3. a constant temperature water jacket; 31. a water inlet; 32. and (7) a water outlet.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Referring to fig. 1, the constant temperature puffing device of the invention comprises a screw puffing machine 1, wherein a puffing screw 2 is arranged in the screw puffing machine 1, and a constant temperature water jacket 3 is sleeved on a casing 11 of the screw puffing machine 1. Wherein, the constant temperature water jacket 3 is connected with circulating constant temperature water through a water inlet 31 and a water outlet 32 to realize the constant temperature function.

According to the invention, the constant-temperature water jacket 3 is sleeved on the casing 11 of the screw expander 1, and food is rolled and extruded in the screw expander 1 and is fed forward along the axial direction of the expanding screw 2, so that the food can exchange heat with the constant-temperature water jacket 3 through heat conduction of the inner wall of the casing 11, thereby ensuring that the food is in a certain temperature range in the extruding and expanding process of the food, and preventing the food from being coked due to overhigh temperature and insufficient curing degree caused by overlow temperature.

As a preferred embodiment, the thermostatic water jacket 3 is integrally connected with the housing 11 to ensure the thermostatic efficiency of the thermostatic water jacket 3.

Specifically, the screw extruder 1 is a single screw extruder or a twin screw extruder. The invention is suitable for two existing single-screw puffing machines and double-screw puffing machines, and particularly for the double-screw puffing machine, because the contact frequency of food and the inner wall is high, the constant temperature effect in the food puffing process is better.
