Invention of a machine to grind spinach, sweet vegetables like MSG, the whole village admires a Quang Tri farmer

According to Mr. Huy, Dai An Khe banh tet has long been famous for its deliciousness and its characteristic feature is that the cake is green and shaped like a crescent moon.

To make the moon cake, in addition to the ingredients of fragrant, shiny sticky rice grains and the filling of fatty meat and green beans, the important factor is that the sticky rice must be soaked and mixed immediately with water pounded from Malabar spinach leaves to create both the green color and the characteristic delicious flavor.

However, to have water spinach leaves, the households making banh tet in Dai An Khe village have to work quite hard. Previously, people mainly used the traditional method of pounding spinach leaves by hand in a mortar.

Later, a more advanced method was to use a blender to grind, then filter and squeeze the juice, but the productivity was low, time consuming and expensive.

From the essential needs of his family and the households making moon cakes in the village, Mr. Huy came up with the idea and successfully researched and manufactured a multi-purpose blender with a compact size, low cost, easy to disassemble and repair. The machine system consists of 2 main parts: a "blender" with 1 cutting blade and a "juice press" with a spiral shaft.

In addition, there is an electric motor and a transmission unit. All are placed on a sturdy iron frame. After being washed, the fresh green spinach leaves are put into a vertical shaft with a cutting blade inside to be ground finely, then transferred to a spiral shaft to extract the juice.

The blended and pressed mixture is taken out through two separate doors, one door is the spinach juice, the other door is the spinach residue after pressing.

According to Mr. Huy, using a multi-function blender helps increase labor productivity 10-15 times compared to the previous manual method, and the cost of households making banh tet is also significantly reduced.

“With 100 kg of Malabar spinach leaves, if done manually, it would take 5 workers a day to grind and squeeze the juice, costing about 1 million VND. Meanwhile, with a multi-function blender, it would only take about 1 hour and cost 150,000 VND,” said Mr. Huy.

Not only meeting the increasing demand for grinding Malabar spinach leaves of households making moon cake in Dai An Khe village and other households in the district, Mr. Huy's multi-function grinder also serves the people's need to grind other types of food.

According to Mr. Huy, Dai An Khe village has now established the Dai An Khe Moon Cake Cooperative with more than 20 participating households.

On average, each household brings to the market thousands of banh day, banh tet and banh chung of all kinds every day. During the Lunar New Year, the number of orders from households in the cooperative is very high, about 100,000 cakes of all kinds.

Therefore, his successful manufacture of a multi-purpose blender has contributed to serving the needs of households in the cooperative. It helps save time, labor, increase economic efficiency and ensure food safety.

“Because I researched and manufactured it myself, I hope to receive guidance and technical details from scientists and experts to further improve productivity, quality, and economic efficiency,” Huy added.

Chairman of the Farmers' Association of Hai Thuong Commune (Hai Lang District, Quang Tri Province) Le Van Thao said that not only serving local needs, Mr. Huy's multi-function blender also meets the needs of households in the district to blend and extract juice from spinach leaves, ramie leaves, etc. to make cakes.

Thereby, not only meeting the increasing demand of the market but also contributing significantly to helping the moon cake product achieve the provincial 3-star OCOP certification.

Mr. Thao added that in addition to inventing the multi-function blender, Mr. Huy is also famous for his "cool hand" in repairing agricultural machinery in the locality.

Damaged mowers and harvesters in his hands are not only restored but also upgraded to become machines for growing crops.

His mechanical workshop annually brings in an income of 120 - 150 million VND, provides vocational training and creates regular jobs for 3 local workers.
