an internal heater

Abstract

An internal heater, comprising: a cylinder, forming a closed inner cavity together with two end faces; The large opening is aligned with the upper end surface of the barrel and there is a gap between the two; the shroud, the shroud is detachably arranged on the straight part of the shroud, the outer edge of the shroud is in contact with the side of the shroud There is a set vertical distance between the upper end surfaces, and the fluid boiled from the tubes passes through the guide tube and then sprays to the guide cover; among them, 1) The ratio of the inner diameter of the straight tube of the guide tube to the inner diameter of the cylinder is 0.375~ 0.5; 2) The height-to-diameter ratio of the inner cavity of the cylinder is 1.5-2.5; 3) The width of the gap between the guide tube and the cylinder is 10-40mm; 4) The outer edge of the guide cover and the upper surface of the guide tube The distance between the end faces is 125-600mm. The invention effectively eliminates the foam formed in the boiling process and avoids the phenomenon of overflowing the pot. During the use of the equipment, the adjustment is simple and flexible.

Description

technical field [0001] The invention relates to an internal heater, in particular to an internal heater used for a boiling pot in a saccharification workshop of a brewery. Background technique [0002] The boiling pot is a large energy-consuming beer factory. How to achieve an appropriate total evaporation and shorten the boiling time under the premise of ensuring the quality of wort is the key factor for energy saving and consumption reduction. [0003] In the prior art, most brewery boiling pots use internal heaters. The heating principle is: the steam entering the shell side from the bottom of the internal heater will exchange heat with the wort in the tube side, and the steam will exchange heat to the Wort (steam becomes condensed water after heat exchange), so that the wort rises from the tubes of the inner heater, accelerates through the guide tube to reflect and disperse in the guide cover, and completes the wort from the inside to the outside Convective circulation ...

AI Technical Summary

Problems solved by technology

The existing internal heater often has the problem of boiling over the pot or too much foam during the boiling process, causing the foam layer to cover the entire liquid surface of the wort. After elimination, boil again, thereby limiting the total evaporation of wort, prolonging the boiling time, and at the same time having a certain impact on the quality of wort
