Low-temperature camellia seed oil cold-pressing process

The invention relates to a low-temperature camellia seed oil cold-pressing process. The process comprises the main steps: warehousing and checking camellia seeds, cleaning and removing impurities, drying and controlling moisture, vibrating and discharging, warming the seeds and shelling, buffering and temporarily storing, pressing, settling and filtering. The process is characterized in that 1, the moisture is controlled, and the steps of flat-plate drying, storage bin ventilating, steam hot-blast stove moisture drying and cooling and storing are combined; 2, seed warming and shelling are carried out; 3, buffering and temporary storing are carried out, the seeds drop from the storage tank by vibrating during pressing; and 4,pre-pressing and pre-squeezing are carried out. The process is high in mechanical automation degree, the camellia seeds in different moisture contents can be dried and subjected to quality guarantee, and packaging and pouring after drying are not required when the seeds are stored for a long time after drying or are continuously squeezed after drying. Meanwhile, the problem that the kernel rate in the shells is extremely high after shelling is solved, the quality in the total process is well controlled, the process is simple and convenient to operate, and the oil extraction rate and the camellia seed oil quality are improved. The manual packaging and discharging cost is saved by 40 RMB for each ton of camellia seeds. The yield of the camellia seed oil in a two-screw unit is increased from the original 15 tons per day to over 30 tons per day, and the residual oil is reduced from the original 10-12 percent to 7-9 percent.
