Mango dryer helps upgrade Vietnam's fruit king industry

Mango is one of the five largest fruits in the world, with its output second only to grapes, citrus, bananas, and apples. Its production scale ranks third among tropical fruits and is known as the "King of Tropical Fruits". Mango can be planted in Vietnam throughout the year, and the current mango planting area in Vietnam is approximately 87000 hectares. Vietnamese mango has a long supply period and sufficient supply, starting from September each year and ending in June the following year. Moreover, Vietnamese mango varieties are mainly Da Qing Mango, with strong competitiveness in price.

The air energy fruit dryer is used to dry mango slices in time to make fragrant dried mango, improve the added value of mango and extend its shelf life. According to the production capacity and site requirements of Vietnam's Fruit King, about 4 tons of mangoes need to be dried every day. In the early stage, it was equipped with dual 15P hosts and a matching drying room.

The structural composition of Hello River Brand Mango Drying Machine is as follows: 1. Heat pump heating unit. 2. Insulation box device. 3. Hot air circulation device. 4. Automatic moisture removal device. 5. Intelligent control device. The entire system of the main drying oven adopts SUS304 stainless steel inner plate design. The entire box is equipped with a 30MM thick polyurethane insulation layer, which has good thermal conductivity. The patented air distribution system independently designed and developed ensures uniform air speed and heat distribution in the drying room, and there are no dead corners when drying at 360 ℃. The material quickly dries without mold, reducing the drying time. Completely cycling and sealing, completely recovering heat, can achieve zero heat loss during the drying process, and improve energy utilization efficiency.

Special attention should be paid to the materials and insulation conditions used in the mango drying room. Mango drying requires much higher insulation requirements for the drying room than traditional methods. Currently, most drying rooms use polyurethane boards as insulation layers, and the inner and outer skins are made of colored steel, stainless steel, or galvanized sheets. The installation is relatively simple, and it is a lock buckle type on-site assembly. The specific steps for the renovation and construction of the drying room are: installation of the bottom plate → installation of the vertical plate → installation of the top plate → installation of the bottom plate reinforcement plate (convenient for workers to use carts for work and cleaning the drying room) → installation of the main machine → installation of the circulating fan → installation of the air duct board or uniform air plate → connection of the power cord and drainage pipe.

Key points of mango drying process 1: Mango slices need to be soaked in sugar solution. During the drying process of mango drying, different temperatures are required at each stage, which has high requirements for temperature and humidity. In the early drying stage, high-temperature drying is required to quickly remove most of the moisture. The heat pump dryer uses high-precision digital sensors from the United States, which can accurately detect temperature and humidity values, At the same time, different parameter data (functional mode, temperature parameters, humidity parameters, etc.) can be set.

Key point 2 of mango drying process: When drying mangoes, white plastic trays should be used to hold mango slices to prevent them from sticking to the tray after drying. The drying quantity determines the size of the baking room and the number of material racks. At this time, it is required that the hot air circulation in the baking room must be uniform. According to the placement of mango slices, a reasonable design of the baking room air path should be made to ensure that there is circulating hot air passing through every corner of the baking room, so as to achieve uniform drying quality.

Key points of mango drying process three: The system time is divided into 5 stages to complete. The first stage is 55 degrees Celsius, with a temperature rise of 3 hours. The second stage is 60 degrees Celsius, with the start of dehumidification. The third stage is 62 degrees Celsius, with continuous dehumidification. The fourth stage is 58 degrees Celsius, with the start of cooling and dehumidification. The last stage is 55 degrees Celsius, with solid dehumidification. When the product reaches the required moisture content for drying, it is generally around 15% -18%. The product can be placed in a sealed container and allowed to soften for 2-3 hours to ensure that the moisture content of each part is balanced and the texture is soft.

Hello River Brand Mango dryer is an energy-saving device that utilizes the process of heat absorption and release of refrigerant to achieve heat transfer and transportation. The characteristic of snow seeds is that they can achieve morphological transformation through heat absorption and release. The evaporator and condenser inside the main machine are the carriers of heat absorption and release, while the compressor is a device that provides power to the entire system. With only a small amount of electrical energy, it can generate a heating capacity equal to 4 times that of electric heating, Moreover, it does not emit harmful substances during operation, does not pollute drying materials, operates intelligently, simply, and conveniently. It is currently an energy-saving equipment subsidized by the state for agricultural machinery, targeting a large number of farmers, with the following characteristics:

1. More cost-effective: Utilizing natural atmospheric heat for effective conversion, temperature regulation and dehumidification are carried out simultaneously, without combustion or electric heating. The drying cost is directly reduced by 70% compared to traditional methods.

2. Faster: Temperature regulation and dehumidification run simultaneously, saving 35% drying time compared to traditional methods.

3. Cleaner: The entire drying process has no combustion, no waste gas or wastewater discharge, and no environmental pollution. There is no chemical rust prevention or paint residue, ensuring that the equipment is 100% pollution-free during the food drying process.

4. More uniform: according to the principle of air fluid mechanics, the most sufficient pipeline design is carried out for the air flow direction and flow rate in the drying room, ensuring the uniform heat distribution in each corner of the drying room, eliminating the dead corner left in the traditional drying method, and solving the most common problems in the drying process at one fell swoop.

5. More intelligent: It can also intelligently control the temperature and humidity of the drying room according to the preservation needs of different drying objects, meeting various drying and preservation requirements.

6. Longer service life: Titanium efficient heat exchange fins, ultra strong corrosion resistance, used for various drying objects, with a service life of up to 15 years.
