Peanut extracting oil and saving kernel apparatus and method and production of albumen powder, peanut powder

Abstract

The invention relates to a device and the process for extracting peanut oil and leaving whole peanut, and relates to albumen powder and peanut powder made from the degreased peanut. The device for extracting peanut oil and leaving whole peanut includes a hydraulic plant and an oil press system. The hydraulic plant controls the oil press system by a piston, and the oil press system is sequentially composed of a drip tray, a lower ejector plate, an oil flowing plate, a press ring, a pressure dish and an upper ejector plate. The invention adopts the low-temperature method for extracting the peanut oil and leaving the whole degreased peanut, pressure is applied slowly and repeatedly, so that the peanut can not be pressed into meal in oil pressing, the whole nutrient content of the peanut is kept, 70%-80% of the fat in the peanut can be removed, the protein can be improved by more than 70%, the food with high protein and low fat can be formed.

Description

Technical field [0001] The invention relates to a device for squeezing peanut oil and retaining whole peanuts by a low-temperature method, and a process for extracting oil and retaining kernels with the device, as well as protein powder and peanut powder prepared from defatted peanuts. Background technique [0002] With the continuous improvement of people's living standards, the consumption concepts of urban and rural residents have undergone major changes. People are no longer satisfied with food and clothing, and pay more attention to nutrition and delicious food. With the development of industry, urban environmental pollution is becoming more and more serious. According to reports, the top four causes of death in Hebei Province are: myocardial infarction, cardiovascular disease, cerebrovascular disease and heart disease, that is, a quarter of people die from these diseases. People's awareness of health care has increased. It is better to treat diseases than to prevent disease...

AI Technical Summary

Problems solved by technology

[0003] At present, high-temperature physical technology is widely used at home and abroad to press peanut oil. Although the degreasing is relatively complete, the shape and nutritional content of the peanut cake produced in the oil production process are destroyed due to high-temperature processing, and the possibility of reprocessing food is lost, so it can only be used. As feed, it causes a waste of valuable peanut protein and other nutrient resources, and also greatly reduces the economic value and processing benefits of peanuts.
