Device and process for removing red skin of peanuts by partitioned temperature control quick cooling at low temperature

Abstract

The invention relates to a device for removing the red skin of peanuts by partitioned temperature control quick cooling at low temperature, which comprises a baking device and a cooling device connected with the baking device, wherein the baking device is connected with a hot source; the cooling device is connected with a cold source; the baking device comprises a power box and three groups of ovens which are connected together; a humidification box is arranged in the front of each group of oven; and the humidity in the humidification box is constant, and a humidity sensor and a peanut conveying belt are arranged in the humidification box. In the device, the peanuts are baked at the low temperature, so the grease quality of the peanuts is not damaged, and the quality guarantee period is not shortened; after being baked, the peanuts are cooled at the low temperature quickly, so that the peanuts can be separated from the skin quickly; the peeling rate of the peanuts is more than or equal to 99 percent, the valve breaking rate of the peanuts is 0 percent, the peanuts are easy to peel, the peeling effect is good, the influence of the peeling process on peanut protein, and a peroxidating value is less than 0.45 mmol / kg; and the automaticity of equipment is high, the working condition of relevant equipment can be adjusted automatically according to the detected equipment state, the work efficiency is improved greatly, and the operation is simple.

Description

technical field [0001] The invention relates to a food machine for deep processing of agricultural by-products, in particular to a device and processing technology suitable for performing low-temperature segmental temperature-controlled rapid cooling on peanuts to remove red coats. Background technique [0002] Peanut peeling devices currently used in the society are generally divided into two types, one is a wet peeling machine, and the other is a dry peeling machine. When the wet peeling machine is peeling, it needs to be sprayed with water first, and then peeled , and its shortcoming is: the wet red clothes of peanuts that take off are not easy to collect, and take off net rate is low, and processing is complicated, time-consuming and laborious, and step is loaded down with trivial details. The dry peeling machine mostly uses gauze or molds for peeling. The main disadvantage of this method is that it is easy to damage the surface of peanuts, and the sand that is worn off ...

[0002] Peanut peeling devices currently used in the society are generally divided into two types, one is a wet peeling machine, and the other is a dry peeling machine. When the wet peeling machine is peeling, it needs to be sprayed with water first, and then peeled , its shortcomings are: the wet red clothes of peanuts are not easy to collect, the removal rate is low, the processing is complicated, time-consuming and laborious, and the steps are cumbersome

The dry peeling machine mostly uses gauze or molds for peeling. The main disadvantage of this method is that it is easy to damage the surface of peanuts, and the sand that is worn off will also pollute the peanuts. Another dry peeling machine It is heated at a temperature above 200°C for more than 60 minutes, and then peeled. Although this peeling machine is easy to peel and separate the peanuts from the red coat, it is easy to crush and damage the peanuts during peeling, forming residual products. At the same time, under high temperature conditions, the peanut oil will be denatured. The higher the temperature and the longer the heating time, the more intense the thermal oxidation polymerization reaction will be. The oil that undergoes thermal oxidation polymerization will contain toxic glycerides Polymer, the oxidation of oil makes the peroxide value increase sharply, and the quality of oil cracks. This polymer is absorbed in the body and combined with the enzyme, which will cause the enzyme to lose its activity and cause a physiological bathing phenomenon, which is harmful to human health. It not only makes peanuts The quality of its own oil has deteriorated, and the shelf life of peanuts has been greatly shortened
