Device and method for continuous treatment on wort

Abstract

The invention provides a device and a method for continuous treatment on wort. The device comprises a buffer tank which is used for storing wort, a heater which is used for heating the wort in the buffer tank and is connected to the buffer tank, a boiling tower which is used for making each part of the wort heated by the heater stay in the boiling tower for the same time and boiling the wort and is connected to the heater, a flash tank which is used for flashing the wort boiled by the boiling tower in vacuum and is connected to the boiling tower, a clarification tank which is used for separating hot coagula of the wort flashed by the flash tank and is connected to the flash tank, and a cooler which is used for cooling the wort clarified by the clarification tank and is connected to the clarification tank. The device and the method can guarantee the consistency of quality of the prepared wort, realize boiling effects, guarantee wort quality, save energy, reduce consumption and reduce exhaust gas discharge, and has a simple structure and a low cost.

Description

technical field [0001] The invention relates to a wort continuous processing equipment and a wort continuous processing method. Background technique [0002] In the past, the following continuous wort treatment equipment and wort continuous treatment method (Mola continuous saccharification process) have been proposed (please refer to image 3 ). In this process, firstly, the filtered wort is heated in the temporary storage tank 1 to raise the temperature from 78°C to 100°C. Then the 100°C wort is continuously sent to the production tank 2 by a pump. The hops are quantitatively added online between the temporary storage tank 1 and the generation tank 2. The generating tank 2 is equipped with a stirrer and a direct steam injector, and the wort is kept in the generating tank 2 for 45 minutes at a temperature of 100°C-104°C. Afterwards, it is continuously transported to the clarification tank 3 to separate thermal coagulation and clarified wort. The clarification tank 3 is ...

AI Technical Summary

Problems solved by technology

Although the high-temperature wort boiling in this process is greatly accelerated at elevated temperatures, using a temperature range of 120-160°C, which is significantly higher than the current temperature range for wort preparation (100-108°C), will lead to an increase in the color of the wort , HMF (hydroxymethylfurfural), DMS (dimethyl sulfide), etc. increase, and a series of shortcomings such as oxidation of reducing substances

In addition, the high-temperature wort in the reaction tube system is likely to cause serious scaling of protein precipitation. Once it occurs, it will be difficult to clean and lead to interruption of continuous production, which violates the requirements of continuous operation.
