A constant temperature gradient control device for single crystal sugar crystallization tank

Abstract

The utility model relates to single crystal rock sugar production equipment technical field, concretely relates to a single crystal rock sugar crystallization tank's constant temperature gradient control device. The utility model provides a single crystal rock sugar crystallization tank's constant temperature gradient control device, including crystallization tank body, constant temperature heating system, temperature detection unit and controller, its characterized in be that: the side wall of crystallization tank body adopts multilayer composite structure, from inside to outside is in proper order: food -grade stainless steel lining layer, heat -conducting aluminium plate layer, vacuum heat preservation layer and engineering plastics shell, the constant temperature heating system includes at least 3 groups of independent temperature control heating unit, and the bottom strong heating area, the middle transition area and the top weak heating area are distributed in the height direction of crystallization tank body inside in ladder form, the temperature detection unit contains multiple groups of temperature sensor that respectively vertically embeds the side wall in heat -conducting aluminium plate layer, and forms the upper, middle, lower three groups annular temperature measurement array.
