Problems solved by technology

However, these methods not only increase construction and equipment investment, but also consume a large amount of energy to increase production costs.
[0008] Due to the low ambient temperature, the toughness of the wheat cortex decreases, and it is easily broken during the process of separating from the endosperm, which not only increases the difficulty of operation, but also affects the balance of the wheat flour milling system and product quality, and increases energy consumption.

Embodiment 1

[0040] A wet and hot air recycling process in a wheat processing process, the process steps are as follows (200 tons of wheat processed per day, 4 moistening wheat silos of 3m×3m×18m, 1 clean wheat bunker with a diameter of 2m and a height of 3m, 1 group of conveying Take the wind network as an example):

[0041] 1. The hot and humid air discharged into the atmosphere by the pneumatic conveying air network is changed into the collection mixer 9 (the mixer adopts a power impeller pressurized type, and the power is equipped with 5.5kw), and then enters the collecting pipe 10 (the diameter of the large end of the collecting pipe). 600mm, small head diameter 200mm, length 12m), the wind speed in the pipe is 16m / s;

[0042] 2. In the corresponding position on the collecting pipe in the central part of the wheat moistening warehouse 1, the opening is connected to the branch pipe 12 in and out of the warehouse. The diameter of the branch pipe into the warehouse is 150mm, the length ...

Embodiment 2

[0048] A process for reusing hot and humid air in a wheat processing process, the process steps are as follows (300 tons of wheat are processed per day, 8 moistening wheat silos of 2m×3m×18m, and a clean wheat bunker with a diameter of 2m and a height of 3m,):

[0049] 1. The hot and humid air originally discharged into the atmosphere of the food workshop is introduced into the collection mixer (the mixer is pressurized with a power impeller, and the power is equipped with 5.5kw), and then enters the collecting pipe (the diameter of the large end of the collecting pipe is 500mm, and the diameter of the small end is 500mm). 300mm, length 14m), the wind speed in the pipe is 12m / s;

[0050] 2. In the corresponding position on the collecting pipe corresponding to the bottom center of the wheat-running silo, open the inlet and outlet branch pipes. The diameter of the branch pipe into the warehouse is 200mm, the length is 1.5m, the wind speed in the pipe is 10m / s, and the regulating...

Embodiment 3

[0056] A process for reusing moist and hot air during wheat processing, the process steps are as follows (200 tons of wheat processed per day, 4 moistening wheat silos of 3m×3m×17m, 1 clean wheat bunker with a diameter of 2m and a height of 2.6m, 1 group of Conveying air net, 1 group of bran drying system as an example):

[0057] 1. The hot and humid air discharged into the atmosphere by the pneumatic conveying air net and the bran drying system is changed into the collection mixer (the mixer is pressurized with a power impeller, and the power is equipped with 7.5kw), and then enters the collecting pipe (collecting The diameter of the large end of the pipe is 650mm, the diameter of the small end is 200mm, and the length is 15m), and the wind speed in the pipe is 18m / s;

[0058] 2. At the corresponding position on the collecting pipe in the center of the wheat-running warehouse, open the inlet and outlet branch pipes. The diameter of the branch pipe into the warehouse is 160mm...

Abstract

The invention relates to a recovery process of energy and materials generated in wheat processing, and provides a recycling process of hot and humid air generated in wheat processing, which is used for adjusting moisture and temperature of wheat. In the process, the hot and humid air generated in procedures such as a production or domestic boiler of a wheat processing enterprise, pneumatic transmission in a production workshop, bran drying, food processing and the like is separately conveyed to wheat bind or conveyed to the bins after being collected and mixed, and then wheat in a wheat wetting bin or clean wheat bin is heated and humidified. By utilizing the recycling process, the energy is utilized maximally so as to realize cyclic economy, wheat wetting time is shortened, bin capacity is reduced, and meanwhile product quality and flour yield are improved.

Description

technical field [0001] The invention relates to a process for reusing the moist and hot air generated in the wheat processing process, in particular to a process for applying the recovered moist and hot air to wheat moisture and temperature regulation. Background technique [0002] In flour processing enterprises, the wheat processing process mainly includes wheat cleaning, moisture adjustment, wheat milling, flour cleaning and sieving, product collection and packaging and other processes. Among them, after the wheat is milled, the material must be lifted to the high square screen for screening through the pneumatic conveying system. In the prior art, the hot and humid air generated by the pneumatic conveying process is separated from the conveyed material, and then directly discharged into the atmosphere through pulse filtration. [0003] In the wheat milling process, in order to meet the needs of the milling process, the moisture distribution ratio of the wheat cortex and...
