Peanut oil physical refining process with low temperature filtration

First, peanut oil filtration process principles and processes cryogenic

Peanut cold filter principle and process of refining the crude oil is low filtration various phospholipids colloidal impurities filtered out process. The principle of this process is based on the different phospholipid molecules and colloidal molecules fat melting point, when peanut oil reduced to a certain temperature, the higher melting phospholipids colloids first crystallization, filtration under certain conditions at this time, the precipitated phospholipids colloids can not pass filter cloth was trapped down the purpose of separation and grease.

Three,Process introduction

1, stirring

From the press shop press squeeze crude oil, is pumped into the cold filter each cryogenic cooling plant pot, while stirring, filter aid (Celite filter aid may be either peanut cake may also be crushed by the rear 18 mesh sieve homemade filter aid), added in an amount of 1% -5% of the crude oil, stirring speed 60r / min, stirred 20min.

2, cooling

After stirring for adding a filter aid circulating water inlet valve open, the oil is cooled by the cooling pot heat exchange coil, the cooling process subcooled pot stirring speed 30r / min, oil temperature dropped from 70 ℃ 20 ℃, Cooling time 4h.

3, raising the grain

After cooling 4h, stirring was stopped, for 4h at 20 ℃, higher melting impurities such as phospholipids colloidal nuclei with filter aid, gradually crystallized cohesion becomes large, the force of gravity to sink down the pot.

4, coarse filter

Using plate and frame filter for the first time filtering, the use of thick cloth, fine double filter, the filter temperature is controlled at 20 ℃ to 25 ℃, smooth filtration pressure, the operating pressure does not exceed 0.3MPa, a grease filter to remove the larger phospholipid gel.

5, second fine filter

Frame filter using a second fine filter, filter cloth using cloth, paper double filtration, filtration pressure to be stable, the operating pressure of not more than 0.2MPa, fine filtration of fine particles to remove grease and other impurities phospholipids colloids. The second fine filter to ensure clear and transparent oil.

Four, process advantages

1, a pre-filter aid request to join, there are two main effects, one for suction, on the other hand from the pre-filter aids.

2, low energy consumption, refining consumption is small, no steam consumption, use of recycled water, no waste emissions.

3, peanut oil filter physical refining low temperature to maximize the retention of nutrients in peanuts, physiologically active ingredients and unique flavor of peanuts. A long time and be able to keep the oil is clear and transparent.
