preparation example Construction

[0015] The invention provides a preparation device for tobacco raw material concentrate, comprising a pre-concentration tank 1, a centrifugal pump 2, a heat exchanger 3, a primary crystallization tank 4, a secondary crystallization tank 5, a micro heat pipe 6, a horizontal centrifuge 7, a washing machine The net tower 8, the pre-concentration tank 1 is used to store the tobacco raw material extract, the outlet end of the pre-concentration tank 1 is connected to the heat exchanger 3 through the centrifugal pump 2, and the outlet end of the heat exchanger 3 is connected to the primary crystallization tank 4 and the secondary crystallization tank 4. The tanks 5 are connected in series successively, the outlet end of the upper part of the secondary crystallization tank 5 is connected with the micro heat pipe 6 and the horizontal centrifuge 7 in sequence, the solid outlet end of the horizontal centrifuge 7 is connected with the washing tower 8, and the liquid of the horizontal centri...

Embodiment 1

[0019] A method for preparing tobacco raw material concentrate, comprising the steps of:

[0020] First, 10 kg of the tobacco raw material extract with a solid content of 8% in the pre-concentration tank 1 is introduced into the heat exchanger 3 (the present embodiment adopts a shell-and-tube heat exchanger) through the centrifugal pump 2, and is generated at a temperature of -5°C. Part of the fine ice crystals are sent to the primary crystallization tank 4 and the secondary crystallization tank 5 for crystallization in turn. The agitator speeds in the primary crystallization tank 4 and the secondary crystallization tank 5 are respectively 200r / min and 300r / min. After 15min, the large ice crystals Gradually grow, and then transport the large ice crystals to the micro heat pipe 6 for slight heating. The temperature of the micro heat pipe 6 is maintained at 40 degrees Celsius, and then sent to the horizontal centrifuge 7 for solid-liquid separation. The separated ice crystals are...

Embodiment 2

[0026] A method for preparing tobacco raw material concentrate, comprising the steps of:

[0027] First, 10 kg of the tobacco raw material extract in the pre-concentration tank 1 with a solid content of 7% is introduced into the heat exchanger 3 (a shell-and-tube heat exchanger is used in this embodiment) through a circulation pump, and some fine particles are generated at a temperature of -7°C. After the ice crystallization, send into primary crystallization tank 4 and secondary crystallization tank 5 to carry out crystallization. The rotational speed of the agitator in the primary crystallization tank 4 and the secondary crystallization tank 5 is respectively 300r / min and 400r / min. After 12 minutes, the large ice crystals gradually grow, and then the large ice crystals are transported to the micro heat pipe 6 for slight heating, and the temperature of the micro heat pipe remains at 50 degrees centigrade, and then sent to the horizontal centrifuge 7 for solid-liquid separatio...

Abstract

The invention provides a preparation device and method of a tobacco raw material concentrated solution. The preparation device comprises a pre-concentration tank, a centrifugal pump, a heat exchanger, a primary crystallizing tank, a secondary crystallizing tank, a micro heat pipe, a horizontal centrifuge and a cleaning tower. The pre-concentration tank is used for storing a tobacco raw material extraction solution. The outlet end of the pre-concentration tank is connected with the heat exchanger through the centrifugal pump, the outlet end of the heat exchanger is sequentially connected with the primary crystallizing tank and the secondary crystallizing tank in series, the upper outlet end of the secondary crystallizing tank is connected with the micro heat pipe and the horizontal centrifuge in sequence, the solid outlet end of the horizontal centrifuge is connected with the cleaning tower, and the liquid outlet end of the horizontal centrifuge is communicated with the outlet end of the cleaning tower and the pre-concentration tank. The concentration solution circulates constantly in the system, and is discharged from an outlet in the bottom of the secondary crystallizing tank after the target requirement for the solid content is met. On the basis of freezing and icing, ice residues are separated to concentrate a tobacco raw material extraction solution; compared with an existing heating concentration method, energy consumption is saved, and effective aroma components can be better reserved.

Description

technical field [0001] The invention relates to the field of tobacco production, in particular to a device and method for preparing tobacco raw material concentrate. Background technique [0002] Domestic paper-making reconstituted tobacco leaves are usually produced by a two-step method. First, the active ingredients of the tobacco are fully soaked in a solvent, and then the tobacco extract is concentrated and backfilled on the tobacco substrate. The key production processes include extraction, concentration, copying, and coating. Wait for the process. Tobacco extract usually contains a certain amount of protein, pectin, cellulose, hemicellulose and other macromolecular substances. These components generally exist in the extract in the form of solid suspensions. Only by separating these solid suspensions can the product quality. Chinese patent ZL200910063930.0 "A new comprehensive impurity removal process and impurity removal system for raw material extract of tobacco she...
