TECHNICAL FIELD
[0001] The utility model relates to the technical field of steam extraction machine, concretely to a tea cake steam extraction machine. BACKGROUND
[0002] In the tea processing process, the production of tea cake is an important link. In the traditional tea cake production process, the desolventizing treatment of tea residue (i.e. the remaining material after tea pressing) mostly relies on natural airing or simple drying equipment. These methods not only have low efficiency, but also cannot effectively control the moisture and volatile components in the tea residue, thereby affecting the quality of the final tea cake. In addition, the traditional equipment often lacks effective stirring and layering treatment mechanism during the processing process, resulting in uneven heating of the tea residue, affecting the desolventizing effect. In order to overcome the above-mentioned defects and improve the efficiency and quality of tea cake production, a tea cake steam extraction machine is proposed to solve the above-mentioned problems. SUMMARY
[0003] In view of the deficiencies of the prior art, the utility model provides a tea cake steam extraction machine, which has good steam effect and good desolventizing effect, and solves the problems mentioned in the background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a tea cake steam extraction machine, comprising a shell, a pre-extraction layer, a drying-extraction layer, a desolventizing layer and a drying layer are sequentially arranged inside the shell, the number of pre-extraction layers is two, the number of drying-extraction layers is three, the number of desolventizing layers is two, and the number of drying layers is one. A water adding device is arranged inside the drying layer. A control material door is arranged on one side of the pre-extraction layer and the drying-extraction layer. A stirring device is arranged inside the shell. A mixed gas outlet and a tea residue inlet are formed at the top of the shell. A tea residue outlet is formed at the bottom of the shell. A heating semicircular pipe is wound on the outer surface of the shell.
[0005] Further, the stirring device is composed of a motor, a speed reducer and a scraper. The scraper is attached to the pre-extraction layer, the drying-extraction layer, the desolventizing layer and the drying layer.
[0006] Further, tea residue falling ports and steam holes are formed inside the pre-extraction layer, the drying-extraction layer, the desolventizing layer and the drying layer, and the tea residue falling ports of each layer are distributed alternately.
[0007] Further, the desolventizing layer has a double-layer double-cavity structure, one cavity is directly connected to steam, and the other cavity is connected to indirect steam.
[0008] Further, a humidifying pipe is fixedly connected inside the shell.
[0009] Further, a communication pipe is fixedly connected to one end of the shell, and a vent is arranged in the middle of the communication pipe.
[0010] Compared with the prior art, the technical scheme of the present application has the following advantages:
[0011] 1. This tea cake steaming and desolventizing machine introduces tea cake containing solvent into the first pre-desolventing layer from the top tea cake inlet. After being heated, the tea cake is pushed and swept by the scraper on the stirring device into the next layer for heating, desolventizing and drying through the tea cake drop outlet, and finally discharged from the tea cake outlet.
[0012] 2. In this tea cake steaming and desolventizing machine, tea cake enters the desolventizing layer for desolventizing treatment. After controlling a certain material layer height by controlling the material gate, the tea cake is desolventized by the scraper on the stirring device. At the same time, direct steam enters the steam hole of the desolventizing layer from the direct steam inlet and sprays out to contact the tea cake for desolventizing. After desolventizing, the mixed gas containing solvent and water vapor is discharged from the connecting pipe to the upper part of the shell, and then discharged from the mixed gas outlet to the condenser. The gas in the drying layer is discharged from the exhaust port, and the steam enters the jacket from the steam inlet for heating. The condensate is discharged from the outlet.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figs. 1-2 The tea cake steaming and descaling machine in this embodiment includes a shell 1. Inside the shell 1, there are sequentially arranged a pre-descaling layer 2, a drying and descaling layer 5, a desolventizing layer 8, and a drying layer 10. There are two pre-descaling layers 2, three drying and descaling layers 5, two desolventizing layers 8, and one drying layer 10. A water adding device 9 is provided inside the drying layer 10. The setting of the water adding device 9 increases the moisture content of the tea cake, which increases customer profits and reduces tea cake dust.
[0018] A control gate 6 is provided on one side of the pre-delamination layer 2 and the drying delamination layer 5. A stirring device 11 is provided inside the shell 1. A mixed gas outlet and a tea meal inlet are opened at the top of the shell 1. A tea meal outlet is opened at the bottom of the shell 1. A heating semi-circular tube 3 is wrapped around the outer surface of the shell 1. The steam has no short circuit and heats up quickly. It is not a pressure vessel. It uses less steam, reduces operating costs, is easy to operate, and is less likely to cause safety accidents. An inspection door 7 is provided on the front of the shell 1.
[0019] This technical solution adopts top free feeding, reducing equipment costs and economic losses caused by auger blockage. A humidification pipe 4 is fixedly connected inside the shell 1, increasing the amount of wet material and reducing the powderiness of the meal while improving the stripping solvent effect.
[0020] The steam inlet, direct steam inlet, and condensate outlet in this technology are all conventional technologies, so they will not be described in detail.
[0021] Additionally, the stirring device 1 consists of a motor 13, a reducer 12, and a scraper. The scraper is attached to the pre-delamination layer 2, the drying layer 5, the desolventizing layer 8, and the drying layer 10. The pre-delamination layer 2, the drying layer 5, the desolventizing layer 8, and the drying layer 10 are all provided with tea meal drop outlets and steam holes, and the tea meal drop outlets in each layer are staggered.
[0022] Furthermore, the desolvation layer 8 has a double-layer, double-cavity structure, with one cavity for direct steam and the other for indirect steam. This reduces the moisture content of the direct steam, which is beneficial for the extraction of tea meal and reduces the agglomeration of tea meal. A connecting pipe 14 is fixedly connected to one end of the shell 1, and an exhaust port is provided in the middle section of the connecting pipe 14.
[0023] The working principle of the above embodiments is as follows:
[0024] (1) The tea cake steaming and desolventizing machine introduces the tea cake containing solvent into the first pre-desolventing layer 2 from the top tea cake inlet. After heating, the tea cake is pushed and swept by the scraper on the stirring device 11 and enters the next layer for heating, desolventizing and drying through the tea cake drop outlet. Finally, it is discharged from the tea cake outlet.
[0025] (2) In this tea cake steaming and desolventizing machine, the tea cake enters the desolventizing layer 8 for desolventizing treatment. After the material layer height is controlled by the control gate 6, the tea cake is desolventized by the scraper on the stirring device 11. At the same time, direct steam enters the steam hole of the desolventizing layer from the direct steam inlet and sprays out to contact the tea cake for desolventizing. After desolventizing, the mixed gas containing solvent and water vapor is discharged from the connecting pipe 14 to the upper part of the shell, and then discharged from the mixed gas outlet to the condenser. The gas in the drying layer 10 is discharged from the exhaust port, the steam enters the jacket from the steam inlet for heating, and the condensate is discharged.
