Intelligent separation equipment and separation method for peanut kernels and peanut skin

Abstract

The invention discloses intelligent separation equipment and separation method for peanut kernels and peanut skin. The equipment includes a gas explosion device, a shifting device, a drying device anda negative pressure adsorption device; the gas explosion device receives conveyed peanut materials with skin to be removed, and through the infiltration of supersaturated steam and a rapid pressure relief method, the materials are subjected to gas explosion under the effect of pressure difference to complete the initial separation of the peanut kernels and the peanut skin; the shifting device shifts the initially separated peanut kernels and peanut skin to enter the drying device; the drying device compresses the outside air for heating, and transfers heat through hot air to heat and dry theinitially separated peanut kernels and peanut skin, so that the peanut skin and the peanut kernels are fully separated; and the negative pressure adsorption device collects the fully separated peanutkernels and peanut skin with different densities and masses through the negative pressure adsorption manner, respectively. The technical solution provided by the present disclosure realizes the intelligent separation of the peanut kernels and peanut skin through the gas explosion method to minimize the impact on the quality of the peanut kernels and the peanut skin.

Description

technical field [0001] The invention belongs to the technical field of separation control, and in particular relates to an intelligent separation device and separation method for peanut kernels and peanut red coats. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Peanut, also known as groundnut, is a kind of nut with abundant yield and wide consumption in my country. Peanut is composed of peanut kernel and its covered seed coat—red coat. Peanut has rich medicinal value. Peanuts are rich in nutrients, containing protein, fat, vitamins, carbohydrates and trace elements. Peanuts also contain physiologically active substances, which have a health care effect on the human body. Pharmacological studies have proved that peanuts have the effects of scavenging free radicals, anti-aging, preventing heart and cerebrovascular diseases and cancer, st...

AI Technical Summary

Problems solved by technology

This processing technology mainly uses the intermittent nature of low-temperature baking and the principle of thermal expansion and contraction of the substance to make the peanut red coat fall off. This method has a high overall efficiency, but there are also the following disadvantages: peanut red coat and peanut red coat After the kernel has been roasted many times, the main nutrients inside it have been destroyed

This treatment method has high efficiency, but there are the following disadvantages: after the red coat is removed, it must be rinsed with clean water to prevent residual lye, which makes the subsequent treatment process complicated; lye itself is a chemical substance that will It reacts with the substance in the peanut kernel or the peanut kernel, causing the quality of the peanut kernel to be destroyed; due to the temperature sensitivity of the peanut kernel and the peanut kernel, the peanut kernel will be significantly affected by the temperature, making the peanut kernel more sensitive to the temperature. It causes damage. If the washing process is not well controlled, there will be residual lye, which will affect the quality of oil and human health.

But this device also has the following disadvantages: First, the uncertainty of the steam heating temperature will change the nutrient content of the material

Secondly: due to the operation of the material in the cooking tank, the accumulation of the material is very serious, so that the saturated steam cannot fully contact the material, resulting in low peeling efficiency

Again: due to the stirring during the cooking process, there will be an operation where the material collides with the stirring spoon, which will cause damage to the material and cannot guarantee its integrity

[0009] It can be seen that the development of existing related devices is not perfect, and the existing red coat removal device is not ideal, and there are problems of low efficiency, insufficient separation, and great damage to materials
