First, Vietnamese chicken farmers' "grinding bitterness": bending down is tired, the dust is heavy, and the chicken has diarrhea. Aunt Nguyen (55 years old) in the suburbs of

Hanoi raises 100 chickens and grinds 2 tons of corn flour every year. She used to use an old-fashioned crusher. Every day I have to face:

I am tired of bending down: I have to put the corn cobs into the feed inlet one by one, and every time I grind the powder, my waist hurts so much that I can't straighten up, and I have to stick plaster to sleep;

I have a lot of dust: there is no dust-proof device, and the dust flies all over the sky when I grind the powder, and my aunt has chronic bronchitis, and every time I grind the powder, I have to wear two layers of masks, but I still choke and cough;

Chicken has loose bowels: The powder ground by the old-fashioned crusher is very coarse, the chicken is not easy to digest, often has loose bowels, the survival rate is only 85%, and more than 10 chickens are lost every year.

Last year, my aunt bought a 9FC320 self-priming corn grinder from a dealer in Ho Chi Minh City, and now her grinding work has become an "easy job":

self-priming feeding. No need to bend down: 1.5-meter-long flexible suction pipe, as long as it is aimed at corn cobs or kernels, the machine automatically sucks in through the centrifugal fan, aunt can operate standing, no need to bend down any more;

The corn is ground into 80-100 meshes of fine powder (which is 3 times finer than that of an old-fashioned hammer mill) by adopting a millstone type structure (high-hardness 65Mn steel), so that the chicken is easy to digest after eating, the condition of diarrhea disappears, and the survival rate is improved to 100%;

Adapt to small generators, which can be used in rural areas: many places in rural Vietnam do not have power grids, so the aunt uses a 5kW small generator to drive the machine, which consumes 1.5 degrees of electricity per hour (about 30,000 VND, about $1.2), and the cost is very low; Easy to

clean, not stuck: feed pipe and millstone chamber are removable design, clean residual corn residue as long as 5 minutes, aunt can do it by herself, do not need to find a maintenance master.

Third, the real use scenario in Vietnam's rural areas: from "hard work" to "sideline"

chicken feeding to save costs: Aunt grinds corn flour and soybean meal to make formula feed, which is 10,000 Vietnamese Dong (about 0.4 US dollars) cheaper than commercial feed per catty. 100 chickens save 3 million VND (about $120) per month;

processing sideline earns extra money: Auntie's son sells ground corn flour to surrounding farmers to make corn porridge and corn cakes, earning 5,000 VND (about $0.2) per catty, earning an extra 2 million VND (about $80) per month;

Cooperative services drive the whole village: The chicken cooperative in the village bought three machines to provide flour grinding services for 50 chicken farmers in the surrounding area, collecting 2000 Vietnamese Dong (about 0.08 US dollars) per catty and earning 6 million Vietnamese Dong (about 240 US dollars) per month, so that all chicken farmers in the village can use the "easy flour grinding" machine.
