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 hot and humid air recycling process in the wheat processing process, the process steps are as follows (200 tons of wheat processed per day, 4 wheat moistening bins of 3m×3m×18m, 1 clean wheat bin with a diameter of 2m and a height of 3m, 1 group of conveying Wind net as an example):

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

[0042] 2. At the corresponding position on the collecting pipe at the central part of the wheat moistening bin 1, the opening is connected to the branch pipe 12 for entering and exiting the bin. The diameter of the branch pipe entering the warehouse is 150mm, t...

Embodiment 2

[0048] A kind of hot and humid air recycling process in wheat processing, the process steps are as follows (300 tons of wheat processed per day, 8 wheat moistening bins of 2m×3m×18m, 1 clean wheat bin with a diameter of 2m and a height of 3m):

[0049] 1. Introduce the hot and humid air from the food workshop into the atmosphere into the collection mixer (the mixer adopts a powered impeller pressurized type, and the power is equipped with 5.5kw), and then enters the collection pipe (the diameter of the large head of the collection pipe is 500mm, and the diameter of the small head 300mm, length 14m), the wind speed inside the pipe is 12m / s;

[0050] 2. At the corresponding position on the collecting pipe corresponding to the central part of the bottom of the wheat conditioning bin, the opening is connected to the branch pipe for entering and exiting the bin. The diameter of the branch pipe entering the warehouse is 200mm, the length is 1.5m, and the wind speed in the pipe is 10...

Embodiment 3

[0056] A hot and humid air recycling process in wheat processing, the process steps are as follows (200 tons of wheat processed per day, four 3m×3m×17m wheat moistening bins, one clean wheat bin with a diameter of 2m and a height of 2.6m, 1 group Conveying wind net, 1 group of bran drying system as an example):

[0057] 1. The hot and humid air originally discharged into the atmosphere by the pneumatic conveying wind net and the bran drying system is changed into the collection mixer (the mixer adopts a powered impeller pressurized type, and the power is equipped with 7.5kw), and then enters the collection pipe (collection The diameter of the big head of the pipe is 650mm, the diameter of the small head 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 moistening bin, the opening is connected to the branch pipe entering and exiting the bin. The diameter of the ...

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 recycling hot and humid air generated during wheat processing, in particular to a process for applying the recovered hot and humid air to moisture and temperature regulation of wheat. 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, the material after wheat milling must be lifted to the high plan sieve through the pneumatic conveying system for sieving. In the prior art, the hot and humid air generated during 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 endosperm is g...
