Problems solved by technology

[0002] The traditional oil production process of oil crops includes hot pressing and solvent extraction. Due to the denaturation of macromolecular nutrients (protein, starch, dietary fiber, etc.) in the cake after using the above process, it can only be used It is used for feed processing or as fertilizer but not used for high added value, resulting in serious waste of resources

Embodiment Construction

[0017] In this embodiment, the oil extraction test is carried out with Fengdan peony seeds, a method for preparing high-yield low-temperature cold-pressed peony seed oil, comprising the following steps:

[0018] S1. Heat the sun-dried and selected peony seeds to 60° C. and keep it warm for 12 minutes; the fluidity of the oil is enhanced at high temperature, and the moisture content in the peony seeds is about 15%.

[0019] S2. Immediately send the shells to the sheller placed in the cold storage for shelling. After shelling, the shells and kernels are separated by the vibrating sieve air selection that is also located in the cold storage, and then sorted by the moldy seed screening device to take out the spoiled kernels. After picking, crush and sieve, crush to 60-80 mesh;

[0020] S3. Immediately heat and spray the enzyme solution after being sent out of the cold storage. The heating temperature does not exceed 40°C. After reacting for 3-5 hours, place it in a drying oven for...

Abstract

The invention relates to a preparation method of cold-pressed peony seed oil with a high oil yield. Peony seeds which are dried in the sun and selected elaborately are heated to 50-60 DEG C, kept at the temperature for 10-12 min and instantly sent to a husking machine in a refrigerator for husking, husk and kernel separation is performed through winnowing by a vibration screen in the refrigerator after husking, kernels which go bad are sorted out through a mildewed seed screening device, grinding and sieving are performed after sorting, the kernels are conveyed out of the refrigerator and heated, an enzyme solution is sprayed, the heating temperature does not exceed 40 DEG C, the kernels are put into a presser to be pressed after being dried and conditioned, the primary pressing temperature and the pressing chamber temperature are both 58 plus or minus 2 DEG C, coarse oil and oil cakes are obtained, the oil cakes are subjected to ultrasonic aided oil extraction, and coarse oil obtained twice is combined. According to the cold-pressing method, the oil yield is remarkably improved and reaches 32%-36% through shock cooling and shock heating type temperature treatment, enzyme treatment and ultrasonic secondary pressing.

Description

technical field [0001] The invention relates to the field of oil extraction of woody oil plants, in particular to a method for preparing peony seed oil with high oil yield and low temperature cold pressing. Background technique [0002] The traditional oil production process of oil crops includes hot pressing and solvent extraction. Due to the denaturation of macromolecular nutrients (protein, starch, dietary fiber, etc.) in the cake after using the above process, it can only be used It is used for feed processing or as fertilizer but not used for high added value, resulting in serious waste of resources. With the improvement of people's awareness of health and comprehensive utilization of resources, people began to explore high-tech for synchronous production of high-quality vegetable oil and low-denatured nutrients in cakes, so as to realize the comprehensive utilization of oil crops. [0003] Cold pressing oil production is a physical method, pressurization does not heat...
