Embodiment Construction

[0017] Such as figure 1 As shown in the oil dewaxing process, the oil to be dewaxed is pumped into the heater 2 through the feed pump 1 of the crystallization tank, and the oil is heated to 50°C to completely melt and enter the crystallization tank 3; Under the program control of the crystallization menu and the action of the cooling medium, it will finally drop to 6-18°C after 18-40 hours to complete the cooling, crystallization and crystal growth of the oil. The crystallization menu is shown in Table 1; the feed pump 4 of the diaphragm filter press and the diaphragm filter press The machine 5 is interlocked controlled, and the filtering process is automatically controlled, and the process of oil feeding, filtering, squeezing, purging, and cake unloading is automatically completed; the crystallized oil is pumped into the membrane filter press 5 through the membrane filter press feeding pump 4 Filter and separate, and the dewaxed grease flows into the dewaxed grease tank 7. W...

Abstract

The invention discloses an oil dewaxing process and an oil dewaxing device. The process comprises: heating oil to be dewaxed till the wax is molten completely, transferring the oil to a crystallizing tank, and subjecting the oil to crystallization and crystal growing according to preset crystallization menu in the crystallization tank; delivering the crystallized oil into a membrane filter press, filtering, transferring the separated dewaxed oil into a dewaxed oil tank, and thus, completing dewaxing. The dewaxing device comprises the crystallization tank, wherein the crystallization tank is connected with the membrane filter press through a feeding pump; and the discharging port of the membrane filter press is connected with the dewaxed oil tank. Compared with the conventional dewaxing process, the process and the device have the advantages that: the need of any aid filtering agent is obviated, so the production cost is effectively reduced; the oil product is natural and environment-friendly, and the loss of oil is low; by wax by product is pure, does not contain any aid filtering agent, can be directly used in industrial production of edible wax, avoids any environment pollution and requires little equipment investment; and the automation degree of the device is high, and the device is more suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a grease dewaxing process and device. Background technique [0002] The oil is processed by dewaxing, which separates the inherent wax in the oil from the oil, improves the nutritional value of the oil, and improves the taste of the oil. The traditional dewaxing process is to rapidly freeze the oil, then add diatomaceous earth as a filter aid to mix with the oil, and pump it into a heat-unloading winterization filter for filtration. The wax is separated by filter cloth and diatomaceous earth. , is trapped on the filter cloth. In this traditional process, when the oil is rapidly cooled, the wax crystallization is not good, and a small amount of wax will penetrate the filter cloth, which affects the quality of the oil. The diatomite added before the wax filtration is mixed into the wax, which affects the purity of the by-products and reduces the value of the by-products. The mixture of wax and diatomite seriously pollutes the e...
