Embodiment 1

[0026] S1, oily bean ultra-drying pretreatment;

[0027] Specifically, the sesame beans with full particles are selected, and the sesame beans are washed with clean water. After the cleaning is completed, the sesame beans are dried in an oven to make the water content less than 8 water.

[0028] S2, heat oil bean and mix it with rice husk;

[0029] Specifically, after heating the oily bean to 80°C to 100°C, it is mixed with the rice husk, and the amount of the rice husk added is 5% of the mass of the oilseed bean.

[0030] S3, adjust the rotation speed of the screw oil press from the original factory setting of 45 rpm to 30 rpm, and add the cold water with 4% of the oil bean mass while adding the mixed material to press to make the pressing process smooth and improve the output. When the oil rate is over 18%, edible oil and soybean cake are obtained.

Embodiment 2

[0032] The difference between Example 2 and Example 1 is that rice husks are not added, and the rest of the operation process and parameter setting are exactly the same as those of Example 1.

[0033] The oil extraction rate in this example is only 10%, and it is found through observation that the material has a high viscosity during the pressing process. Although the pressing process can be carried out smoothly without interruption, the oil extraction amount is not ideal, which is higher than that of Example 1. The rate is nearly doubled, which is mainly because no rice husk is added to reduce the viscosity of the material during the pressing of oily bean.

Embodiment 3

[0035] The difference between Example 3 and Example 1 is that the amount of rice husk added is 3% of the mass of the oilseed bean, and the rest of the operation process and parameter settings are exactly the same as those of Example 1.

[0036] The oil extraction rate in this example is only 14%, and it is observed that the material has a high viscosity during the pressing process. Although the pressing process can be carried out smoothly without interruption, the oil extraction amount is not ideal, which is higher than the oil extraction rate of Example 1. This is mainly because the amount of rice husks added is insufficient, and the viscosity of the material is not well reduced, resulting in an unsatisfactory oil extraction rate.

Abstract

The invention discloses a method for preparing cyperus esculentus edible oil by adopting a spiral oil press, and belongs to the technical field of oil pressing. The problems that when mandulapalka edible oil is produced through an existing spiral oil press technology, the oil yield is low, a press is prone to being stuck and locked by high-viscosity mandulapalka cakes, and continuous operation cannot be conducted are solved. According to the method, the rice husks and the cyperus esculentus are mixed and squeezed to prepare the cyperus esculentus edible oil, the material viscosity in the cyperus esculentus squeezing process is reduced by utilizing the fiber property of the rice husks, the oil extraction rate reaches 18% or above, and meanwhile the locking phenomenon is avoided. The obtained bean cake contains the rice hulls and can be directly used for brewing white spirit, and the rice hulls are added to reduce the viscosity, so that the liquor yield can be increased, the liquor yield of 52-degree or above white spirit brewed with every 100 jin of bean cake meal can reach 42 jin or above, the liquor yield exceeds the liquor yield of 2% points when the rice hulls are not added, and the purposes that the preparation process is simple, and the amount of obtained white spirit is large are achieved.

Description

technical field [0001] The invention relates to a method for preparing edible oil of sesame oil by adopting a screw oil press, and belongs to the technical field of edible oil pressing. Background technique [0002] There are mainly three types of edible oil preparation processes in my country: pressing, leaching and subcritical extraction: (1) Pressing, the production process is basically divided into two types: one is hydraulic, hydraulic manual feeding cannot be industrialized production, and the oil yield is low ( It is only about 12%); the second is screw pressing. Compared with hydraulic pressure, the advantage of this process is that it can be industrialized. However, due to the instant extrusion and temperature rise, for oily bean with high oil and sugar content, the squeeze will increase the viscosity. The press will be locked and cannot be pressed, and the oil will not be produced if it is squeezed loose, and the oil yield is not high (about 12%); (2) leaching, the p...
