Perhaps, the process from a farmer to an amateur inventor of Mr. Dinh Van Giang is no different from his "colleagues" throughout rural Vietnam. When his family was working as a pig raising, every day he saw his wife chopping banana for a dozen pigs, Mr. Giang always thinks about how to get a food mill to help his wife. That thought clung to him until he suddenly saw that a Japanese blender could crush fish and meat, and he came up with a solution for himself: to build a bigger, more capable  machine can grind all the pet food in the house according to the blender principle.

His innovation was not only that, the idea of combining "many in one" to minimize the step in livestock production prompted him to create a 5-in-1 machine that could help the farmer clean up the hashing, crushing, mixing, incubating and even cooking animal feed - an achievement after many improvements and different versions. Mr. Dinh Van Giang proudly introduces the device “with many sizes to adjust, to arbitrary size, any type can be grinded from corn stalks, banana trees, elephant grass, shrimp, crab, fish, snails and etc. A special part of my machine is the heater that works only 3-5 minutes after the machine works, with a temperature of 60-70 degrees C, the bran will be cooked without cooking. For those types of bran that need fermentation, users only need to adjust the temperature from 40-50 degrees, just warm enough to stimulate the yeast."
