(1) Process flow
Raw material acceptance → selection → cutting section → re-selection → immersion brine → rinsing → blanching → cooling → draining → quick freezing → packaging → frozen storage.
(2) Operation points
For the selection of raw materials, it is advisable to use cowpea varieties with deeper color and uniform size. The beans have no obvious protrusions, the tissue is tender, the color is cyan or pale green; the cyan and light green are not mixed. The strips are round and straight, and the diameter of the cross section of the bean strip is about 0.5 cm. There are no pests and diseases, no spots, no miscellaneous beans. Cut and cut the two tips of the beans and check them. Remove the peas, the different beans and impurities, and pay attention to the wormholes. Then cut into 5 cm segments or cut into pellets. The immersed saline was soaked in 2% saline for about 15 minutes to remove floating insects and impurities. Rinse the beans and rinse with water. Blanching in boiling water for about 1.5 minutes, until the color turns bright green, taste no bean flavor. Cool and cool with cold water immediately after blanching. After cooling, remove the clear water with a centrifuge. The frozen pre-treated beans should be frozen as soon as possible, and can be pre-cooled to 0-5 ° C, then sent to the quick-freezer and quickly frozen with a cold air of -35 ° C. The plastic bags for packaging are packaged in 250g or 500g, and then packed in cartons, 10kg per carton. Stable temperature and humidity should be maintained during the frozen storage process.
(3) Quality standards
It is light green or dark green, and has the same color; it has the taste and odor of this variety, no odor; the pods are fresh, the strips are round and straight, the thickness is relatively uniform, the beans have no obvious protrusions, and the food has no coarse fiber.

NVR, the full name of Network Video Recorder, is the storage and forwarding part of the network video monitoring system. NVR works with video encoder or Network Camera to complete video recording, storage and forwarding functions
After entering the 21st century, with the development of network technology, there is an increasing demand for video data storage through the network. The monitoring system with DVR as the core has further developed into a NVR system with network functions.
NVR, namely network video recorder, is the storage and forwarding part of the network video monitoring system. Its core function is the storage and forwarding of video streams. Compared with DVR, NVR has a single function. It does not have analog digital conversion and encoding functions and cannot work independently. It usually works with video encoder DVS or network camera IPC to complete video recording, storage and forwarding functions.
NVR has different product forms. Although its core function is the capture, storage, management and forwarding of network video streams, different companies have different designs to complete these functions and have their own characteristics
