Secondary steam recovery system for saccharification boiling

Abstract

The invention relates to a saccharification boiled secondary vapor recovery system, which comprises a wort kettle and a vertical pipe type condenser communicated together directly through a secondary vapor exhausting pipeline, the hot water outlet pipe of the vertical pipe type condenser is connected at the upper part of a heat energy tank, an overflow pipe is connected at the high liquid level part of the heat energy tank, and a hot water storage tank is connected at the other end of the overflow pipe. The cold water inlet pipe of the vertical pipe type condenser is not only connected with the running water inlet pipe, and but also connected with the cold water inlet pipe of the heat energy tank at the lower part of the heat energy tank, and the hot water outlet pipe of the heat energy tank is extended into the heat energy tank from the top part of the heat energy tank. A water-sealing control vapor exhausting device is connected on the secondary vapor exhausting pipeline adjoin to one side of the vertical pipe type condenser. The vapor can be recovered of high efficiency without using an electric valve and pressuring to the wort kettle, in the saccharification boiled secondary vapor recovery system, the recovered hot water can also be automatically changed storage, the investment of the pneumatic valve can be reduced, not only the maintenance is convenient, but also the costis reduced, and the quality of the product can be ensured. When the vapor is superfluous in the secondary vapor exhausting pipeline, which can be automatically drained to the outside through the water-sealing control vapor exhausting device, and the production safety can be ensured.

Description

technical field [0001] The invention relates to the field of beer production, in particular to a secondary steam recovery system for saccharification and boiling. Background technique [0002] In the past, the secondary steam generated by saccharification and boiling was generally recovered through a secondary steam recovery system using a thin-plate heat exchanger, such as figure 1 As shown, a secondary steam recovery pipeline 3' is connected to the straight pipe 2' of the boiling pot 1', and the secondary steam recovery pipeline is connected to the thin-plate heat exchanger 4', and an electric motor is installed on the secondary steam recovery pipeline. Valve A, an electric valve B is also installed on the straight pipe above the secondary steam recovery pipeline. Since the thin-plate heat exchanger does not have a relatively large space inside, the resistance is relatively high, and the passive heat exchange cannot generate negative pressure relative to the boiling pot. ...

AI Technical Summary

Problems solved by technology

[0004] The invention simultaneously solves the problem that the secondary steam cannot be discharged or condensed in time due to excessive steam or condenser failure in the secondary steam exhaust pipeline, which causes the steam pressure in the cavity connected to the boiling pot, steam exhaust pipeline and condenser. The technical problem of a sharp rise, there is a great potential safety hazard; provide a method that automatically controls the exhaust according to the amount of steam in the steam exhaust pipe, and avoids the steam pressure in the cavity connected to the boiling pot, steam exhaust pipe, and condenser. The phenomenon of sharp rise occurs to ensure the production of safe saccharification boiling secondary steam recovery system

[0005] The invention also solves the technical problem that the original recovery system only has heat energy tanks, and cannot store a large amount of hot water when there is too much heat energy, and the heat cannot be recovered more; it provides a method that automatically dumps and stores heat without using a pneumatic valve when there is too much heat energy. Secondary steam recovery system for saccharification and boiling with effective recovery of heat energy
