Embodiment 1

[0016] First pump 50kg of liquid glacial acetic acid into the head tank; then add 38kg of sodium carbonate into the reactor, close the switch, and raise the temperature of the reactor to 60°C; then slowly add the glacial acetic acid in the head tank into the reactor, and Sodium carbonate was neutralized for 80 minutes to obtain sodium diacetate anti-mildew and insect repellent.

Embodiment 2

[0018] First pump 58kg of liquid glacial acetic acid into the high-level tank; then add 41kg of sodium carbonate to the reactor, close the switch, and heat the reactor to 80°C; then slowly add the glacial acetic acid in the high-level tank to the reactor, and Sodium carbonate was neutralized for 90 minutes to obtain sodium diacetate anti-mildew and insect repellent.

Embodiment 3

[0020] First pump 70kg of liquid glacial acetic acid into the head tank; then add 45kg of sodium carbonate into the reaction kettle, close the switch, and heat the reaction kettle to 90°C; then slowly add the glacial acetic acid in the head tank into the reaction kettle, and Sodium carbonate was neutralized for 90 minutes to obtain sodium diacetate anti-mildew and insect repellent.

Abstract

The invention relates to a sodium diacetate grain mildew and insect repellent which is prepared from the following raw materials in parts by weight: 50-70 parts of glacial acetic acid and 38-45 partsof sodium carbonate. The sodium diacetate mildew and insect repellent is mainly used in a grain warehouse, has dual mildew and insect repellent effects on original grain and is a high-efficiency and low-toxicity mildew-proof agent; about two kilograms of grain mildew and insect repellent is used in each ton of rice, thereby being safer compared with an existing product and incapable of causing human and animal poisoning. The sodium diacetate grain mildew and insect repellent provided by the invention can be used for insect prevention and treatment of finished grain such as rice and flour, cereals and oilseeds products such as noodles and rice noodles, and beans such as soybeans, green beans, broad beans and peas, and is suitable for the mildew and insect repellence of various grain and bean products.

Description

technical field [0001] The invention relates to the field of biochemical industry, in particular to sodium diacetate, an anti-mildew and insect-proof agent for grain. Background technique [0002] Raw grain anti-mildew and anti-insect is a new industry in grain storage, which needs to be further improved. Raw grain storage pests are an important reason for the loss of farmers and the national grain storage center. There are more than 200 kinds of stored food pests in my country, but the main stored grain pests in Hunan Province are as follows. Corn elephant (also known as iron grain cow), wheat moth (commonly known as moth), grain beetle, broad bean elephant, mung bean elephant, red lentil bean, red corn beetle and book lice, etc. (1) Corn elephant: (commonly known as Tiegu cattle) shaped like an elephant trunk, corn elephant is a kind of gnawing pest, its eggs, larvae, pupae and pre-hatched adults all grow and develop in a grain of grain, and its development humidity range...
