Problems solved by technology

However, during the pretreatment process of cottonseed, the characteristics of cottonseed determine that the powder degree of the material is relatively large, which affects the effect of oil extraction, the quality of crude oil and the normal and continuous operation of the equipment (including free state lint) during oil extraction. Impact)
The cottonseed processing methods given in the prior art 2006101070878 and 200610115238 mentioned respectively "using a cold rolling mill with a cooling device to extract oil" and "using a low-temperature screw press to directly perform low-temperature oil extraction on cotton kernels", but did not provide How to control the temperature rise during pressing for low-temperature cold pressing, and the specific process of cottonseed pressing is not given
In the known pressing process of the prior art, the temperature rise of the extruded material during pressing can reach above 115°C; if the cold pressing process does not pay attention to special control, the temperature rise can reach above 95°C

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with specific examples.

[0014] The present invention can adopt following process route:

[0015] Cottonseed→cleaning→hulling→separation of kernel and shell→conditioning→forming→dryinggranular material

[0016] After the cottonseed is cleaned according to the conventional method, the heavy impurities, short fibers and dust are removed, and the shelling process is carried out.

[0017] When peeling, according to the existing technology, the gap between the toothed rollers can be adjusted properly according to the moisture and cashmere content of the cottonseed itself, so that the cottonseed kernel can be completely separated from the cotton shell during peeling; since there is no need to control the powder degree, the peeling Compared with the prior art, the process becomes simpler and easier to control.

[0018] When separating the kernel and shell, through sieving and cleaning, the mass ...

Abstract

The invention relates to a process for pre-treating cotton seed, which specifically comprises cotton seed cleaning, peeling, separating kernel and shell, modifying, forming and drying so as to obtain granules. The process is characterized in that 1) after the cotton seed is cleaned and peeled, the kernel and the shell are separated; during the separation of the kernel and the shell, the shell content in the kernel is controlled at 8 to 18 percent, and the kernel content in the shell is controlled to not more than 0.5 percent; 2) during modifying, the moisture is controlled at 12 to 18 percent, preferably, 14 to 16 percent; and the temperature is controlled below 60 DEG C, preferably, 40 to 50 DEG C; 3) during forming, the barrel pressure is controlled; the temperature of the materials is controlled to not more than 90 DEG C, preferably, 70 to 85 DEG C; the oil outlet amount is controlled to not more than 16 percent; and the linearity of the formed granular material is controlled to not more than 10 millimeters; and 4) during drying, the moisture in the dried material is controlled to not more than 5 percent. The method is simple, the process is easy to control, the cotton seed protein is kept not to denature when the cotton seed is pretreated under low temperature, the cotton seed powder is little during peeling and cannot be used as a control index, and the obtained material can be directly used for grease leaching process.

Description

technical field [0001] The invention relates to the technical field of cottonseed processing, in particular to a cottonseed pretreatment process. Background technique [0002] Chinese patent 00134520.6 provides a method for processing cottonseed. In this method, the cottonseed is pretreated at low temperature without pressing, and the protein in the cottonseed is not denatured. It can be used to remove the toxic substance gossypol from the cottonseed to prepare cottonseed protein. However, during the pretreatment process of cottonseed, the characteristics of cottonseed determine that the powder degree of the material is relatively large, which affects the effect of oil extraction, the quality of crude oil and the normal and continuous operation of the equipment (including free state lint) during oil extraction. Impact). The cottonseed processing methods given in the prior art 2006101070878 and 200610115238 mentioned respectively "using a cold rolling mill with a cooling dev...
