Description

Full-automatic bulking device

Technical Field

The utility model relates to a microwave and electromagnetic type puffed food processing equipment, especially a full-automatic popped device.

Background

Corn puffed foods, such as popcorn, are a favorite food product. The corn kernels are heated to 200-240 ℃ to be popped, so that the crisp taste is realized. Furthermore, various seasonings are added in the prior art, so that the taste of the popcorn is better.

A typical popcorn maker uses a pot-shaped configuration to fry the corn kernels with a flavoring until the corn kernels pop to form the popcorn. The problem of the scheme is that 1 is that the efficiency is lower, only intermittent production can be realized, the whole efficiency is lower, the difficulty of realizing automatic control is higher, and manual participation is required through feeding. 2, to wrap corn kernels and seasonings evenly, oil needs to be doped into the seasonings to ensure that the seasonings can flow, and more oil intake affects the health of people. 3, the flavor is influenced, the gasification temperature of part of flavor substances in the seasoning is lower than 200 ℃, and the heating temperature of the corn kernels is 200-240 ℃, so that a large amount of flavor substances are lost, and the taste is deteriorated. For example, the popcorn maker disclosed in patent document CN15100994A, the heating system of the electromagnetic popcorn device disclosed in CN 205727954U, and the electromagnetic popcorn device have such problems.

But wherein the specific construction of the bulking machine is not described in detail. The production line of the scheme is also long, and the scheme adds the seasonings into the syrup to produce products with different tastes, so that the influence on the flavor of the seasonings is large, and the flavor of the seasonings cannot be ensured. And the scheme still adopts a stirring and mixing scheme, and grease needs to be added.

Two ways of heating corn kernels are commonly used in the prior art, one being microwave heating, for example, CN1622764A describes a sweet and salty microwave popcorn composition and products containing these popcorn, and the microwave popcorn is shown in fig. 7 as microwave-heated corn kernels (25) and microwave-heated popcorn (26), which have a high degree of popping, very loose and unsightly shape, and readily absorb moisture. The popcorn is suitable for eating immediately after being popped, is not easy to preserve and has poor selling phase.

Another is an electromagnetic heating method, such as the fully automatic feeding electromagnetic popcorn machine described in CN 111642694 a, which can process popcorn that is nearly spherical and beautiful, but not as crisp as microwave-heated popcorn.

The description in the background art is only for the description of the technology, so as to facilitate the understanding, and the content of the research on the corresponding technology by the utility model is included, and is not in the prior art.
