Cooling device of dough mixer and dough mixer including the same

Abstract

The invention discloses a cooling device of a dough mixer. The cooling device comprises a flour barrel, a rotating shaft and a sealing mechanism. A heat exchange cavity is formed between the inner wall of the flour barrel and the outer wall of the flour barrel. The rotating shaft is fixedly connected with the flour barrel and is provided with a water inlet channel and a water outlet channel; the first end of the water inlet channel and the first end of the water outlet channel extend in the axial direction of the rotating shaft; and the second end of the water inlet channel and the second endof the water outlet channel are communicated with the heat exchange cavity. The sealing mechanism comprises a shell, a mechanical seal and an isolation piece; the shell is provided with a water inletcavity, the mechanical seal is arranged in the water inlet cavity; and the mechanical seal comprises two movable rings and two static rings. The isolation piece is arranged between the two movable rings; a water inlet hole is formed in the rotating shaft along the radial direction; two ends of the water inlet hole are respectively communicated to the first end of the water inlet channel and the water inlet cavity; the first end of the water outlet channel penetrates the side curved wall of the rotating shaft or the end, away from the flour barrel, of the rotating shaft. The flour barrel of thedough mixer is cooled by the cooling liquid, so that the consumption of ice water is reduced. The invention also discloses a dough mixer.

Description

technical field

[0001] The invention relates to the technical field of cooling devices, in particular to a cooling device for a dough mixer and a dough mixer including the device. Background technique

[0002] The dough mixer is a kind of pasta machine, and its main function is to mix flour and water evenly. A large amount of flour and water can be filled by the noodle bucket (or noodle tank, material bucket) to carry out large-scale kneading. However, during the dough kneading process of the dough kneading machine, the temperature will gradually increase, and the excessively high temperature will cause the fabric to be pasted; Ice water is injected into the bucket (or the noodle tank, which is the barrel used to hold the fabric) (the ice water is broken by an ice crusher and then reconciled). Obviously, according to the existing dough mixer structure, injecting ice water directly into the noodle barrel through the water pipe can indeed cool down the fabric, but it needs t...
