Aofu Macadamia nut air heat pump automatic drying, environmental protec

Macadamia nuts, also known as Hawaiian fruit, are known as the "King of Nuts in the World" because of their high oil content and delicious taste. So, do you know what it takes to eat Hawaiian nuts from picking to eating? Hawaiian fruit has two layers of pericarp and endocarp. The outer pericarp is green, and the endocarp is hard and brown. Fresh Hawaiian fruits need to be peeled and dried just after harvesting. Drying is a very critical part of the processing technology of Hawaiian fruits. It directly determines the shelf life and the taste and quality of the final product. Hawaiian fruits just harvested contain about 30% moisture. The drying time is controlled in 70 hours, which can reduce the moisture content to less than 5%, and the fruit will also shrink. To the inside of the shell, it is separated from the inner wall of the shell, so that when the fruit breaks the shell, it will not damage the kernels.

However, natural air drying is greatly affected by the weather, and easy to be contaminated with dust impurities, which makes it difficult to control the quality of finished products. Coal-fired drying has the shortcomings of air pollution and fruit odor, requiring special duty, long drying time and difficult to control the quality. In recent years, in order to meet the customer's use requirements, Aofu Industries is committed to independent innovation, research and development of air-energy heat pump drying nut equipment, instead of coal energy drying at the same time to achieve better drying effect. Make full use of technological advantages to transform a new way of nut processing, and promote the development of nut industry to a higher level.

Using airenergy heat pump to dry nuts only needs to build a nut drying room, and then can be used repeatedly for a long time. The fruit is placed in the drying room, and the heat energy in the air is absorbed by the heat pump unit to form a hot air. The hot air flows into the drying room, which makes the air temperature rise greatly and evaporates the moisture of the fruit. Because of the barrier of the drying room, the fruit will not suffer secondary pollution. As long as there is electricity in the drying place, the heat pump can be started, which avoids the problems of sunshine weather and the environmental protection of boiler drying, saves a lot of time and speeds up the whole process of nut processing. At the same time, it is equipped with the intelligent control system of microcomputer. According to the characteristics of drying materials, the drying can be carried out in stages, and the corresponding temperature and humidity can be controlled, so that the drying process can be accurately controlled without the influence of weather and season.

Recently, customers in Yingjiang County, Yunnan Province, used Ofu Industrial Air Energy Heat Pump to dry Hawaiian fruit. According to customer feedback, the Hawaiian fruit was dried by coal burning before, and the quality of the dried product was uneven. After adopting the Ofu Industrial Air Energy Heat Pump Drying Unit, it saves money and saves heart, does not need special person on duty, and the operation is very simple. The quality of the dried Hawaiian fruit is high and stable. After calculation, the cost of nut drying by Ofu Industrial Air Energy Heat Pump Drying Unit is as low as 0.08 yuan/kg, which greatly improves the economic benefits. OEF airenergy heat pump drying is really safe, environmentally friendly, energy-saving and efficient, it is worth recommending.

Fresh nuts are picked and shelled by special nut sheller. After shelling, nuts are screened by screening machine. The selected nuts are transported to the drying room. The nut drying machine can process more than 30 tons of nuts per batch. The drying cost is as low as 0.08 yuan/kg. After drying, the packaged seam packaging bags are automatically exported to ensure the needs of customers.

1. The whole processing process is automated to avoid the mistakes caused by manual operation.

2. All conveyor belts and the operation of machines are controlled by frequency conversion machines, which can effectively adjust the speed of conveyor and operation according to the site conditions.

3. The design of airenergy heat pump drying room avoids the problems of sunshine, bad taste and environmental protection, saves a lot of time and speeds up the whole process of nut processing.

4. Highefficiency wind design: circulating air design is adopted to ensure that the temperature and humidity in every corner of the room are uniform and equal, and forced dehumidification is a strict control of the humidity of the room, and there will be no deviation. The mixing of fresh air into the circulation ensures that there will be no excessive temperature deviation in the room.

5. Safety and durability: adopt the special high temperature compressor of American grain wheel, advanced heat pump system design, multiple effective measures to reduce the exhaust temperature and compression ratio of compressor (such as EVI technology, refrigerant regeneration and supercooling technology etc.), prolong the service life of main engine;

6. Maintenance cost is low: using general high temperature environmental protection refrigerant, low maintenance cost, not destroying the ozone layer, protecting the environment; non-manufacturer self-made mixed refrigerant, also avoiding the dependence of later maintenance on the manufacturer;

7. Easy to use and maintain: The unit is controlled automatically by micro-computer, which has many protective functions, simple to operate, and can be operated and maintained by non-professionals.

8. Better quality: Heat pump drying is a kind of mild drying method, close to natural drying, the evaporation rate of surface moisture is close to that of internal surface migration, which ensures the good quality, good color and high product grade of the dried products.
