The landlord can consider buying a stainless steel dining mobile car with a gas stove and a gas bottle. This kind of car is generally driven by manpower, and all kinds of pots and pans are heated by gas. In addition, try to keep the heated box lunch well, which can also save electricity and gas.
If the landlord wants to install a battery car, he can consider customizing a small gas stove with a stainless steel shell in the hardware processing shop. Angle steel is used as the skeleton, with gas stoves and gas cylinders inside and stainless steel sheets outside. Then put it on the bucket of the electric tricycle. Put the cooked box lunch in an insulated container-for example, pile the box lunch on the top of an insulated stainless steel barrel filled with hot water (the hot water will boil before going out), and keep the box lunch warm with the steam from the hot water below. If the hot water is cold, boil it with a gas stove and pour it back into the heat preservation barrel.
