Problems solved by technology

[0003] The current drying of cotton meal is mainly carried out through a drying tower. The current drying tower has several layers, and the upper layers are drying layers. For drying, there is a layer of lower material layer at the lower part of the drying layer, and the cotton meal is cooled during the natural feeding process of the lower material layer. The protein of the cotton meal produced by this method is unstable, the color is poor, and the residual oil is high, and the solvent oil cannot Fully recovered, resulting in higher dissolution consumption

Embodiment 1

[0036] Example 1: refer to Figure 1~5 , is a schematic structural diagram of the drying tower in Example 1 of the present invention, the drying tower includes a cylindrical tower body and a stirring mechanism, the stirring mechanism includes a motor (71), a stirring shaft (72) and a stirring fin (73) , the space in the tower body consists of 6 layers, from bottom to top are discharge layer (1), cooling layer (2), drying layer (3), air-permeable layer (5), drying layer and pre-desolvation layer (6 ), the lower part of each layer is provided with a sieve-shaped partition, and the stirring fins (73) are arranged above the sieve-shaped partition, and in each layer, the partitions are provided with densely distributed feeding holes, Make the partitions sieve-like.

[0037] The partitions under the cooling layer (2), drying layer, breathable layer (5) and pre-desolvation layer (6) are interlayer hollow plates.

[0038] The cooling layer (2) includes a sandwich hollow plate body...

Embodiment 2

[0046] Example 2: refer to Figure 6 , is a schematic structural diagram of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is: the air outlet A (24) of the cooling layer (2) [or the air outlet of the air-permeable layer (5) C (54)] The outlet is not facing upwards, and it is realized by setting a side-opening tower cap on the air outlet A (24) [or air outlet C (54)] to prevent the material from flowing out of the air outlet A (24) ) [or air outlet C (54)] channel into the cavity of the sandwich hollow plate.

Embodiment 3

[0047] Example 3: refer to Figure 7 , is a schematic structural diagram of Embodiment 3 of the present invention. Compared with Embodiment 2, the difference of this embodiment is: the air outlet A (24) of the cooling layer (2) [or the air outlet of the air-permeable layer (5) C (54)] is realized by setting a multi-pass tubular body on the air outlet A (24) [or air outlet C (54)].

Abstract

The invention discloses a method for drying and desolventizing cottonseed meal and special drying and desolventizing equipment of the method. The cottonseed meal is dried and desolventized by virtue of a drying tower, wherein the drying tower comprises a tower body and a stirring mechanism; the interior of the tower body comprises at least 5 layers, namely a discharging layer (1), a cooling layer (2), a drying layer (3), a ventilating layer (5) and a pre-desolventizing layer (6) sequentially; a partition board below the cooling layer (2), the drying layer (3), the ventilating layer (5) and the pre-desolventizing layer (6) is a sandwich hollow sheet; steam is directly input from the ventilating layer (5) and cooling gas is directly input from the cooling layer (2); the drying layer (3) and the pre-desolventizing layer (6) are used for indirectly heating by virtue of steam; and various layers are formed with material level regulating holes and corresponding material level regulating mechanisms for regulating the height of a material layer. Compared with the prior art, the drying and desolventizing method and the drying and desolventizing equipment disclosed by the invention can be used for effectively solving problems of an existing cottonseed meal protein treatment process which is instable in product, poor in color, high in residual oil, high in solvent consumption and the like, and the stable quality of the cottonseed meal protein is guaranteed.

Description

technical field [0001] The invention relates to a method for drying and desolventizing cotton meal and special drying and desolventizing equipment thereof. Background technique [0002] Cotton meal is a by-product of cottonseed oil extraction, which needs to be dried before it can be further turned into commercial meal. [0003] The current drying of cotton meal is mainly carried out through a drying tower. The current drying tower has several layers, and the upper layers are drying layers. The lower part of the drying layer is provided with a lower material layer, and the cotton meal is cooled during the natural feeding process of the lower material layer. The protein of the cotton meal produced by this method is unstable, the color is poor, and the residual oil is high, and the solvent oil cannot Fully recovered, resulting in higher dissolution consumption. Contents of the invention [0004] The purpose of the present invention is to provide a method for drying and des...
