Prior to the 1950s, food production and processing were mainly manual operations, which basically belonged to traditional workshop production methods. Only a small number of food processing plants with industrialized production methods in some large cities along the coast, the equipment used is almost all foreign equipment. The food processing plant is slightly better than the food processing plant. This stage of industrial production of food processing plants is mainly based on the industrial production and processing of flour. But similarly, the equipment used in flour mills is almost entirely foreign. It can be said that before the 1950s, there was almost no decent factory specialized in manufacturing food machinery.
