Description

Technical Field

[0001] The utility model belongs to the technical field of oil processing, and in particular relates to a phospholipid cooling system. Background Art

[0002] At present, the lecithin system production process uses an oil foot pump to send oil foot at about 50°C from the oil foot temporary storage tank to the oil foot conditioning tank. The oil foot is tempered in the oil foot conditioning tank, and the neutral oil is removed and the lecithin is retained by indirect steam and material stirring and homogenizing temperature control to form a lecithin solution at about 80°C. The lecithin solution is then pumped into a lecithin dryer through a gear pump for drying. In the lecithin dryer, the lecithin solution is heated to 110-130°C by steam under a negative pressure of 0.07-0.09Mpa to remove about 40% of the water in the lecithin solution to form concentrated lecithin, which is then pumped into the lecithin temporary storage tank through a pipeline for storage.

[0003] The temperature of the concentrated lecithin entering the lecithin temporary storage tank is 110-130°C. During the storage in the lecithin temporary storage tank, the concentrated lecithin loses heat slowly. During storage, the concentrated lecithin will darken in color due to the high temperature, affecting the product quality. Moreover, when the temperature of the concentrated lecithin is lower than 60°C, the fluidity will decrease, thereby affecting the difficulty of transporting the concentrated lecithin from the temporary storage tank. Utility Model Content

[0004] The purpose of the utility model is to provide a lecithin cooling system to solve the problem that the concentrated lecithin temperature is too high to affect the product quality and the fluidity is reduced when the temperature is too low. The technical solution adopted by the utility model is as follows:

[0005] A lecithin cooling system comprises an oil foot conditioning tank, a first gear pump, a lecithin dryer, a buffer tank, a second gear pump and a lecithin temporary storage tank which are connected in sequence, wherein a third gear pump is arranged on the outlet pipe of the lecithin temporary storage tank, a first coil is wound around the oil foot conditioning tank, a second coil is wound around the lecithin temporary storage tank, two ends of the first coil and two ends of the second coil are correspondingly connected via a water pipe, and a circulating pump is arranged on the water pipe.

[0006] Furthermore, a material level meter is provided on the upper part of the buffer tank, and a first frequency converter is provided on the second gear pump. The material level meter and the first frequency converter are linked via PLC.

[0007] Furthermore, a second frequency converter is provided on the circulation pump, a temperature transmitter is provided on the pipeline between the phospholipid temporary storage tank and the third gear pump, and the second frequency converter and the temperature transmitter are linked via PLC.

[0008] Furthermore, a first valve is provided between the cache tank and the second gear pump.

[0009] Furthermore, a second valve is provided between the phospholipid temporary storage tank and the third gear pump.

[0010] Furthermore, an overflow pipe is provided at the top of the cache tank.

[0011] Furthermore, a third valve is provided on the overflow pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The first coil on the oil foot conditioning tank is connected to the second coil on the lecithin temporary storage tank. The first coil, the second coil and the water pipe for connection therebetween constitute a cooling water circulation pipeline. Circulating water is arranged in the cooling water circulation pipeline. The circulating water takes away the heat of the lecithin temporary storage tank through the second coil, and releases heat to the oil foot conditioning tank through the first coil, so that the temperature of the lecithin in the lecithin temporary storage tank is rapidly reduced. At the same time, the heat-absorbing circulating water is connected to the first coil to heat the oil foot in the oil foot conditioning tank. The hot water is circulated, which can not only ensure the color and fluidity of the concentrated lecithin product, but also use the heat for heating the oil foot, thereby reducing energy consumption.
