Problems solved by technology

[0003] Although the prior art has solved the fresh-keeping problem of fresh Cordyceps sinensis to a certain extent, it is all carried out manually, these technologies are far from meeting the actual needs, and face the following defects: one, the fresh-keeping effect is not ideal, the fresh-keeping time is short, and it is easy to be damaged by freezing and produce Browning seriously affects the appearance, taste and nutrition of fresh Cordyceps sinensis, and it cannot maintain its freshness for a long time; second, the cost of manual operation is high, and the operation is cumbersome. Manually controlling the preservation temperature and humidity brings a lot of inconvenience and is also extremely imprecise. And the production efficiency is low, it is difficult to ensure real-time monitoring and timely adjustment
While the quick-freezing treatment is easy to damage the fresh Cordyceps sinensis, the residual moisture in the disinfected towels and the spraying of honey water not only greatly increase the labor cost, but also do not do it accurately, and also bring a lot of inconvenience to freshness preservation, which is not conducive to industrial production

Embodiment 1

[0029] Place the washed fresh Cordyceps in the quality inspection device for automatic screening, and the screened fresh Cordyceps weighing ≥0.5g is automatically sent to the pre-cooling room, pre-cooled at 4°C for 1 hour, and the pre-cooled fresh Cordyceps is sent to the cold storage room, set the automatic temperature control conditions (when the storage time is ≤ 3 days, the temperature is -4°C and the humidity is 65%; after that, the temperature is reduced by 1°C and the humidity is increased by 0.8% every 5 days, until the temperature reaches -8°C and the humidity reaches 75% % remained stable). And pass the pre-cooled mixed gas under balanced humidity conditions, the mixed gas ratio is 3% O 2 , 23%CO 2 , 74%N 2 , when O 2 When the concentration range is exceeded, the oxygen concentration sensor will automatically alarm.

[0030] After the refrigerated time reaches 75 days, the following quality inspections are carried out:

Abstract

The invention relates to an intelligent fresh-keeping system of fresh cordyceps sinensis. The intelligent fresh-keeping system comprises a quality detection device, a precooling chamber and a refrigerating chamber, wherein the quality detection device is provided with a weight inductor; the precooling chamber maintains the constant temperature of 4 DEG C; the refrigerating chamber comprises temperature control equipment, a wetness balance machine and an oxygen concentration inductor; the precooled fresh cordyceps sinensis is conveyed to the refrigerating chamber, an automatic temperature control condition is set well for the temperature control equipment, the wetness balance machine is used for balancing the wetness, and precooled mixed gas is guided, wherein the compounding ratio of the mixed gas is that O2 is 3-5%, CO2 is 19-23%, and N2 is 74-76%; and when O2 exceeds the concentration range, the oxygen concentration inductor can automatically send an alarm. According to the intelligent fresh-keeping system of fresh Chinese caterpillar fungus, provided by the invention, parameters of the cold-storage fresh-keeping temperature, time, wetness and the like can be intelligently adjusted and controlled in a programmed manner according to the self characteristics of the fresh cordyceps sinensis, and the fresh vitality and the nutrient components of the fresh cordyceps sinensis are maintained from the cell tiers.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of medicinal edible fungi, and relates to an intelligent fresh-keeping system for fresh Cordyceps sinensis, so that the fresh Cordyceps sinensis can be kept fresh for a long time. Background technique [0002] Cordyceps sinensis is a high-grade nourishing and precious Chinese medicinal material, which contains various active ingredients such as nucleosides, polysaccharides, sterols, fatty acids, proteins, peptides and volatile components. As well as regulating blood lipids and other functions, the fresh Cordyceps sinensis after harvest can retain the active ingredients in it to the greatest extent. With the development of Cordyceps sinensis industry, people's nutritional demand for fresh Cordyceps sinensis is also constantly expanding and improving, and the long-term preservation technology of fresh Cordyceps sinensis has gradually attracted people's attention. [0003] Although the prior a...
