Description

Technical Field

[0001] This utility model belongs to the field of bread processing technology, and in particular relates to a low-temperature drying device for high-gluten flour for toast. Background Technology

[0002] The quality of toast bread largely depends on the quality of its raw material, high-gluten flour. High-gluten flour has a high protein content and good gluten quality, which is key to making toast. Controlling the moisture content of flour during production and storage is crucial; excessive moisture can easily lead to clumping and mold growth, affecting product quality and shelf life. Therefore, drying is an important post-processing step in flour processing. Traditional hot air drying methods use high temperatures, which can easily denature the proteins in the flour, damaging the gluten network structure and reducing the flour's baking performance, making it unsuitable for processing high-grade flour specifically for toast. Therefore, low-temperature drying technology has gradually become an ideal choice for processing heat-sensitive materials.

[0003] However, existing technologies still have the following drawbacks: First, the device lacks a dedicated leveling and shaping mechanism for powdery materials like flour. During the drying process, uneven material thickness leads to uneven heating, with some areas under-drying while others are over-dryed, affecting the uniformity of the final product. Second, its heating method is relatively simple, typically using bottom or side heating, making it difficult to evenly and stably transfer heat to the entire material layer, posing a risk of localized overheating. For high-gluten flour requiring precise temperature control, this uneven temperature can still damage its gluten proteins. Therefore, we provide a low-temperature drying device for high-gluten flour specifically for toast, to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0022] Please see Figures 1 to 5 This utility model is a low-temperature drying device for high-gluten flour for toast, including a drying box 1. The drying box 1 is the main container of the device, providing a sealed drying environment to ensure that the internal temperature, pressure and humidity are controllable. The drying box 1 also supports the installation of other structures and prevents external air from entering through a sealing design, thus ensuring the stability of the low-temperature drying process. A heating chamber 2 is installed on the bottom of the drying chamber 1. The heating chamber 2 is installed on the bottom of the drying chamber 1 and is used to store and circulate the heat medium. It mainly pumps the heat medium into the circulation pipe 202 of the heating plate 201 through its internal pump body to achieve uniform heat transfer, thereby maintaining constant heating of the drying tray 3 at a low temperature and preventing the flour from denaturing due to high temperature. The heating plate 201 is installed inside the drying chamber 1, which is located directly above the heating chamber 2. The heating plate 201 transfers heat evenly to the drying tray 3 through heat conduction, so that the flour is heated evenly and achieves low-temperature drying. The heating plate 201 can avoid local overheating and ensure the quality of the flour. A drying tray 3 is provided on the upper end face of the heating plate 201. The drying tray 3 is used to hold high-gluten flour. A scraper plate 304 is slidably provided inside the drying tray 3. The scraper plate 304 is used to scrape the thickness of the flour inside the drying tray 3 to promote uniform drying. A vacuum component 4 for evacuating the inside of the drying box 1 is fixed on the upper end face of the outside of the drying box 1. It should be noted that the vacuum assembly 4 includes a vacuum pump, a vacuum gauge, a vacuum valve, and a cold trap structure, which are used to evacuate the inside of the drying chamber 1, reduce the air pressure inside the drying chamber 1, lower the boiling point of water in the flour, and enable the flour to dehydrate quickly at low temperatures, reduce energy consumption and maintain the nutritional components of the flour. At the same time, the heating chamber 2 is equipped with a heater to heat the heat medium inside it.

[0023] Specifically, a rectangular frame 301 is provided directly above the drying tray 3. The rectangular frame 301 serves as a support structure for the scraper plate 304, guiding the movement of the scraper plate 304 and ensuring that the scraper plate 304 slides smoothly on the drying tray 3. The H-shaped frame 301 is installed on the inner wall of the drying oven 1 by a locking plate 303. A travel opening 302 is provided through the upper end face of the H-shaped frame 301. A movable rod 305 passing through the travel opening 302 is fixed to the upper end face of the scraper plate 304. The movable rod 305 allows manual movement to control the lifting and sliding of the scraper. A circular plate 306 is bolted to the end face of the movable rod 305 passing through the travel opening 302. The circular plate 306 serves as the movable rod 305. The limiting device of 05 prevents the movable rod 305 from coming out of the stroke port 302 and provides an operating handle. The circular plate 306 is in contact with the upper end face of the H-shaped frame 301. The protrusions at both ends of the scraper plate 304 are in contact with the upper end face of the drying tray 3. The movable rod 305 at the upper end of the scraper plate 304 is fitted with a spring 307. The spring 307 provides elastic cushioning to ensure that the scraper plate 304 is stably in the drying tray 3. The upper end of the spring 307 abuts against the lower end of the H-shaped frame 301.

[0024] Furthermore, a pressure relief safety valve 102 is installed on the outer wall of the drying chamber 1, and a sealing door 101 is hinged to the front end face of the drying chamber 1. The valve 102 is installed as a pressure relief device to prevent the internal pressure of the drying chamber 1 from being too high and causing danger. The sealing door 101 provides inlet and outlet channels and ensures the sealing of the drying chamber 1.

[0025] The inner cavity of the heating plate 201 is equipped with a circulation pipe 202. The use of the circulation pipe 202 forms a heat medium circulation channel, allowing the heat medium to flow between the circulation pipe 202 and the heating box 2, thereby achieving efficient heat transfer. Both ends of the circulation pipe 202 pass through the lower end of the heating plate 201 and are connected to the inside of the heating box 2. One end of the circulation pipe 202 is connected to the port of the pump body inside the heating box 2.

[0026] The operation process of this embodiment is as follows: First, open the sealing door 101, spread the high-gluten flour evenly on the drying tray 3, control the scraper plate 304 through the movable rod 305, so that the scraper plate 304 slides on the drying tray 3 to scrape the flour evenly, ensuring that the thickness is consistent, close the sealing door 101, and check the sealing performance of the drying box 1. The vacuum assembly 4 is activated to evacuate the inside of the drying chamber 1, reducing the internal pressure. At the same time, the pump in the heating chamber 2 is activated to circulate the heat medium in the circulation pipe 202 and the heating plate 201, thereby heating the drying tray 3. The flour inside the drying tray 3 is dried in a low-temperature environment. After drying, the heating chamber 2 and the vacuum assembly 4 are turned off first. The pressure is restored to normal through the safety valve 102 or by slowly opening the sealing door 101. Then the dried flour is taken out.
