Fresh-cut vegetables refer to the use of fresh vegetables as raw materials, after cleaning, dressing (peeling), grading, cutting or cutting, color protection, sterilization, weighing, packaging, etc. A new type of processed product that is immediately consumed by consumers or used in the food and beverage industry. Compared with canned fruits and vegetables and quick-frozen fruits and vegetables, it has the characteristics of fresh quality, convenient use and nutritious hygiene.
The main technical contents of fresh-cut lettuce: (1) Selection of special lettuce varieties for processing requires large ball size, short stems, crisp green leaves, good storage and transportation, good taste, and the varieties have heat resistance, cold resistance, anti-convulsions and resistance Disease; (2) Fresh-cut lettuce cultivation and nutrient regulation technology, according to the nutrient absorption rules of N, P, K and trace elements in the growth process of lettuce, propose the best fertilization type, proportion, quantity and period, which can effectively prevent nutrient deficiency Physiological diseases, prolong the shelf life of vegetables; (3) Preservation and quality control of fresh-cut vegetables, and fresh-cut vegetables are mainly processed through the treatment of low temperature, air-conditioning and food additives to maintain the quality of vegetables, prevent browning, and prevent rot; No residue, no pollution disinfectant and acidic electrolyzed water, cleaning, dehydration, packaging of fresh-cut vegetables, control quality; (4) Fresh-cut lettuce packaging technology, selection of packaging materials suitable for carbon dioxide permeability, preservation of fresh air , Extend the shelf life of vegetable products; (5) Adopt GMP and HACCP certifications in accordance with internationally recognized vegetable product quality and safety management systems. The certificate, the quality of self-control management of the whole fresh-cut vegetable processing process, to effectively protect the safety and quality of fresh-cut vegetable products. The application of this production and management technology can increase the technical content of vegetable processing, improve product quality, extend the shelf life of products by 3-7 days, increase the added value of products by 2-5 times, increase the income of farmers, and increase the efficiency of enterprises.
Installing Bullet Solar Camera
1. Understand how solar monitoring works
The solar Security Camera mainly relies on its attached solar panel to convert the solar light into electricity and charge the built-in battery for monitoring. The integrated inverter in the monitoring can also convert the DC power from the solar panel to AC power, so as to provide power when the sun comes out. It is stored in its rechargeable battery during the day, and its power can maintain the continuous work of solar monitoring at night.
2. What are the advantages of solar monitoring over ordinary monitoring
Unlike wired common monitoring, it does not need to run wires to connect it to the power supply. They connect to the home safety system via a Wi Fi connection rather than a data cable. As a result, they are true wireless security solutions that are easier to install. With wired cameras, you need to place them on the wall where the power cord runs, or close to the wall outlet. In contrast, you can install additional solar monitoring anywhere, even if there is no outlet nearby.
3. Which functions are necessary in solar monitoring
Camera resolution, field of view, solar panel wattage, night vision, motion activation, remote monitoring and smartphone alarm. The resolution of the camera determines the sharpness of the monitored safety picture. Look for models with High Definition (HD) cameras or better. The field of view describes the coverage of the camera. Security monitoring with a wider view is always better. Night vision and motion activation indicate whether the camera can see at night and start recording when it detects motion in the coverage area. The wattage of the solar panel paired with the security camera indicates how much power it can generate from sunlight. The battery panel with higher wattage can charge the attached battery faster and provide more power for monitoring. Smartphone alerts and remote monitoring are designed to help you monitor your home or office in the absence.
4. Whether the sun monitoring can continue to work in cloudy days
The answer is yes. The solar panels connected to the solar monitoring system generate less power in cloudy and rainy days, but the excess power stored in rechargeable batteries in sunny days can help them survive rainy and cloudy days.
