I don’t know what you want to ask. I guess you want to solve the problem of heat pre servation of vegetables. You don’t need to heat every grid. You make a large grid to hold water. Then make a small grid on the big grid that can hold the vegetable pot. Fill the large grid with hot water, and place the vegetable basin on the small grid above the water. If the water does not cool the dishes, they will be hot. For water heating issues, you can bring two thermos bottles for boiling water. If there is a power source nearby, you can directly use the water heater to heat it. You can also bring a blowtorch and burn the bottom of the large grid to heat the water. In fact, I personally feel that I don’t have to think about how to heat it, as long as it can keep it warm, after all, it only lasts a morning or an afternoon. Make your own foam insulated box similar to the one used to hold popsicles. The insulation is good, saves trouble and is convenient.
The price of Internet celebrity light boxes for push cart stalls is calculated based on material, size, and quality. A double-sided one of 50 times 120 centimeters costs 200 yuan. Generally, the price is 100, 150, 200, etc. if it is no more than 120 centimeters. The larger one is between 180 and 240 per square, which is calculated as a single side, and the double-sided cost is twice as much. There are also many kinds of light boxes, including ultra-thin light boxes. Different quality and price are different. From the light source, LED lamp curtain, shell material, and power supply, these different qualities have different prices.
