Description
Technical Field
The invention relates to the technical field of food processing, in particular to a stack type processing device and a stack type processing method for shell materials.
Background
The momordica grosvenori contains rich vitamin C, 400-500 mg of vitamin C and rich glucoside, fructose, glucose, protein, lipid and the like in every 100g of fresh fruits, and is one of the first approved medicinal and edible materials in China. The fruit is spherical or oblong, and has a length of 6-11cm and a diameter of 4-8 cm.
But the water content of the momordica grosvenori is as high as 70-80 percent, and the sugar content is higher. In particular, the mature fresh momordica grosvenori contains rich protease, and if the momordica grosvenori is not sterilized and enzyme-killed in time after being picked, the momordica grosvenori is easy to go moldy and go bad and breed bacteria. The cold storage mode is adopted for storage, so that the cost is high, the loss is avoided, and the storage period is short. And the drying can effectively reduce the water content of the material, prevent the growth of microorganisms, reduce the enzyme activity and slow down a plurality of chemical reactions, thereby prolonging the shelf life of the momordica grosvenori. The dried fructus Siraitiae Grosvenorii has retained nutrients, prolonged shelf life, and convenient transportation and storage. In recent years, the yield is increased sharply along with the rapid enlargement of the planting area of the momordica grosvenori. The rottenness and deterioration caused by untimely drying and processing cause a great deal of resource waste. Therefore, how to rapidly dehydrate and dry the momordica grosvenori is an urgent problem to be solved in the momordica grosvenori processing industry.
Regarding the existing drying technology at present, hot air drying is the main drying mode of momordica grosvenori at present due to the simple technology and mature and reliable equipment. However, there are the following problems.
Firstly, blanching and enzyme deactivation are not thorough, so that the siraitia grosvenorii is browned and deteriorated. The easily discolored agricultural product materials need blanching and enzyme deactivation treatment before being dried by hot air. Blanching, also known as enzyme deactivation, refers to a process of subjecting cut fresh fruit and vegetable raw materials to high-temperature heating treatment, and aims to inactivate oxidases such as polyphenol oxidase (PPO) and Peroxidase (POD) in the fruits and vegetables and avoid browning phenomena of the fruits and vegetables and loss of nutritional flavor in a hot air drying process. Meanwhile, the blanching can also reduce pollutants and microbial biomass of fruits and vegetables, remove the unpleasant odor of the fruits and vegetables and simplify the processing process. The hot water blanching and the steam blanching are common blanching methods at present, and have the advantages of simple operation, low equipment investment and the like. However, a large amount of waste water discharged in the hot water blanching processing link easily causes environmental problems such as water eutrophication and the like. However, since the momordica grosvenori has a dense outer shell, it is difficult for the heat of steam blanching to penetrate the outer shell into the interior of momordica grosvenori. In addition, when steam is rapidly introduced into the drying chamber, air in the material can form 'air resistance', and water vapor is further prevented from entering the material. If when high temperature high pressure steam is scalded, carry out trompil processing to the mangosteen earlier, carry out evacuation processing again, then reducible material inside "air lock", afterwards, directly pour into the inside of the mangosteen with high temperature high pressure steam, can follow the inside direct realization of material and scald enzyme deactivation. The influence of the tight shell of the momordica grosvenori is received, the moisture evaporated by the fruit pulp is difficult to be discharged outwards during drying, the hole opening treatment is carried out on the momordica grosvenori, the inside water vapor is facilitated to be discharged outwards, the intermittent vacuumizing can also directly pump the water vapor inside the fruit shell out of the drying chamber, and the drying speed is further improved. Therefore, after the pores are opened in the momordica grosvenori, blanching and enzyme inactivation are carried out by combining a pressure swing technology, and drying treatment is carried out, so that a cheap and effective way for dehydrating and drying the momordica grosvenori is possible.
Secondly, the drying time is long, the drying is uneven, and the loss of nutrient components is serious. In the hot air drying technology, hot air is used as a heat carrier and a moisture carrier. The heat required by material temperature rise and water evaporation is provided by hot air, and the evaporated water is taken away by the hot air, so that the energy utilization rate is low, and the drying time is long. In addition, wet materials close to a hot air inlet in the hot air drying chamber are dried quickly, and materials far away from the inlet are dried slowly, so that the materials in the material tray are dried unevenly. The long-time contact with hot air of material easily leads to heat sensitive nutrient composition to degrade, reduces the dry quality of mangosteen. Therefore, the existing common hot air drying method needs to be innovated.
Vacuum drying, also known as resolution drying, is to put the material under vacuum negative pressure, reduce the boiling point of water and reduce the contact time of the material and oxygen, and can effectively improve the drying efficiency and quality generally. However, the common vacuum drying technology usually adopts a vacuum degree or vacuum pressure maintaining mode, so that the water vapor partial pressure on the surface of the material and the water vapor partial pressure in the vacuum drying chamber easily form a balanced state, the humidity gradient on the surface of the material is reduced, and the improvement of the drying efficiency is not facilitated. The vacuum pulse drying technology is developed on the basis of the common vacuum drying technology, and the continuous periodic pressure switching is adopted, so that the equilibrium state of the evaporation of the moisture on the surface of the material can be continuously broken, and the drying process is accelerated; the continuous pulsation change of the pressure in the drying chamber can also enable the micro pore canals of the dried materials to be continuously expanded and contracted and even communicated with each other, thereby effectively promoting the transmission of the water in the drying chamber to the outside and maintaining higher drying speed. Compared with common vacuum drying, the technology has the advantages of high drying efficiency, good product quality and the like. However, at the instant of pressure switching, if the temperature of the external air is too low, the water vapor in the drying chamber is condensed, and the effect is not good. If the vacuum drying chamber is used for air inlet, external cold air is converted into hot air by virtue of the high-temperature heating wire, and the hot air is directly injected into the momordica grosvenori, so that a temperature gradient from inside to outside can be formed, and the rapid dehydration of the materials is facilitated.
