Problems solved by technology

At present, there are mainly the following methods for oil hydrolysis: 1. Decomposer method. This method is simple to operate, low in equipment costs, and has a wide range of raw material oils and fats. Contains benzenesulfonic acid, discharged into rivers to pollute water sources
2. High-pressure catalase-free continuous hydrolysis method. This method has simple process, high degree of hydrolysis and low energy consumption, but the cost of equipment is high, which is not suitable for small and medium-sized enterprises.
3. Oil plus enzyme hydrolysis method, this method has the advantages of less energy consumption, low equipment cost, high hydrolysis rate, etc., but the production cost is very high

Embodiment 1

[0012] Example 1: Weigh 120Kg of rapeseed oil and put it in a saponification reaction kettle, add 720Kg of tap water, start heating in an oil bath, and the temperature of the oil bath is 110-140°C. At the same time, 26.05Kg of NaOH (industrial grade, content 95%) was weighed and dissolved in 80Kg of water, and the NaOH solution was added to the reaction kettle at one time to start saponification. After saponification for 3 hours, take a little soap liquid every half hour to measure its saponification value, when the saponification value=93.73%, it is the end point of saponification. Transfer the soap liquid to the slurry soap storage tank for cooling, when the temperature of the soap liquid drops to 70°C, accurately weigh the anhydrous CaCl 2 (Industrial grade) 56.49Kg, dissolve in 60Kg water, slowly add CaCl 2 The solution was stirred rapidly, and a large amount of precipitate was obtained. Fully wash the precipitate in the washing tank until the pH value is 7, then press a...

Embodiment 2

[0013] Example 2: Weigh 100Kg of soybean oil and put it into a saponification reaction kettle, add 840Kg of tap water at the same time, start heating in an oil bath, and the temperature of the oil bath is 110-140°C. At the same time, 18.73Kg of NaOH (industrial grade, content 95%) was weighed and dissolved in 60Kg of water, and the NaOH solution was added to the reaction kettle at one time to start saponification. After saponification for 3 hours, take a little soap liquid every half hour to measure its saponification value, when the saponification value=94.69%, it is the end point of saponification. Transfer the soap solution to the slurry soap storage tank for cooling, when the temperature of the soap solution drops to 50°C, accurately weigh the anhydrous CaCl 2 (Industrial grade) 23.54Kg, dissolve in 60Kg water, slowly add CaCl 2 The solution was stirred rapidly, and a large amount of precipitate was obtained. Fully wash the precipitate in the washing tank until the pH va...

Embodiment 3

[0014] Example 3: 130Kg of sunflower oil was weighed and added to a saponification reaction kettle, and 700Kg of tap water was added at the same time, and oil bath heating was started, and the temperature of the oil bath was 110-140°C. At the same time, 25.58Kg of NaOH (industrial grade, content 95%) was weighed and dissolved in 80Kg of water, and the NaOH solution was added to the reaction kettle at one time to start saponification. After saponification for 3 hours, take a little soap liquid every half hour to measure its saponification value, when the saponification value=94.31%, it is the end point of saponification. Transfer the soap solution to the slurry soap storage tank for cooling, when the temperature of the soap solution drops to 40°C, accurately weigh the anhydrous CaCl 2 (Industrial grade) 39.17Kg, dissolve in 100Kg water, slowly add CaCl 2 The solution was stirred rapidly, and a large amount of precipitate was obtained. Fully wash the precipitate in the washing...

Abstract

A process for preparing the calcium salt of long-chain fatty acid used as the additive of high-energy feed for milk cow, meat ox, or meat chicken includes such steps as mixing natural plant oil with NaOH solution, saponifying at 95-98 deg.C, depositing in CaCl2 solution, washing, dewatering, drying and pulverizing. Its advantages are high energy density, and high effect to supplement energy and calcium.

Description

technical field [0001] The invention relates to a preparation method of long-chain fatty acid calcium salt used as a high-energy feed additive, in particular to a preparation method for producing long-chain fatty acid calcium salt by substituting natural vegetable oil for animal oil. Background technique [0002] In the past, the long-chain fatty acid calcium salts produced in my country were produced from animal fats such as tallow and sheep oil, and they were all produced in manual workshops. With the outbreak of mad cow disease, my country has banned the addition and use of animal feed in ruminants. Therefore, using natural vegetable oil instead of animal oil to produce fatty acid calcium meets the requirements of "green" nutritional feed additives. The key technology of the long-chain fatty acid calcium salt preparation process is oil hydrolysis technology. At present, there are mainly the following methods for oil hydrolysis: 1. Decomposer method. This method is simpl...
