Acetic Acid Fermenter Tank 3000L deep fermentation Saccharification Tank

3000L self-priming acetic acid deep fermentation tank acetic acid seed tank fermenter saccharification tank

Bioengineering Principles

Formation of acetic acid

To ensure the effective work of this microorganism, a very ideal working environment is required, namely:

• constant fermentation temperature
• optimal oxygen supply
• Appropriate concentration ratio between material and bacteria
• Nutritional ingredients to maintain the continued vitality of bacteria

As long as the above conditions are met, the fermentation will proceed smoothly without any problems.

1. Overview

The first-level seed tank is a place for the growth of aerobic microorganisms. This equipment introduces German technology and is widely used in my country's vinegar industry and is well received by users.

2. Advantages

This equipment consumes relatively little power, can maintain the air required for fermentation, and can separate vapor and liquid into even contact. 70% to 80% of the oxygen in the inhaled air is utilized, making the conversion rate of alcohol into acetic acid reach 96%. ~97%, giving priority to air compressors and other common air systems, saving air compressors and air purification system equipment. It occupies a small area, improves production efficiency, increases conversion rate, saves 3% of investment equipment, facilitates automation, saves labor, has a simple structure, good dissolved oxygen effect, is hygienic, easy to clean, and easy to operate.

3. The main structure is mainly divided into four parts

1. Tank body: The tank body is cylindrical, with oval heads at the top and bottom. The upper head has an exhaust port, a manhole, an air inlet, and the tank body has a thermometer measurement port, a sampling port, and a cold water outlet.
2. Cooling and heating jacket: It adopts a jacketed screw blade type cold and tropical zone, with water inlets and outlets at the top and bottom. All organisms produced in the fermentation liquid are supported by heat exchange at the water inlet and outlet to maintain the temperature for microbial fermentation.
3. Self-priming transmission: composed of motor, coupling, bearing frame, transmission shaft, sealing rings at both ends, etc.
4. Self-priming device: It is a curved leaf self-priming device, consisting of a rotor and a stator.

4. Inflating principle of self-priming first-level seed tank

Before starting the rotor, first immerse the rotor with fermentation liquid, and then start the motor rotor to start rotating in the stator. The liquid and air are thrown toward the outer edge of the impeller under the action of centrifugal force, and are evenly distributed through the guide plate of the stator. Due to the rotation of the rotor, Due to the stirring effect, the vapor and liquid form fine bubbles around the impeller, and mix and tumble in the strong turbulence, spreading throughout the tank. Therefore, the self-priming aeration device completes the aeration while stirring. And because the air sucked by the rotor forms tiny bubbles, the gas and liquid are closely and evenly combined and contacted. The gas-liquid contact surface is constantly updated to increase the dissolved oxygen coefficient, improve the utilization of oxygen by microorganisms, and promote the healthy growth of bacteria.

7. Instructions for use and maintenance

Close all valves, open feed valve 2, open vent valve 7, feed to 70%-75% of the container, close feed and vent valve 7, open steam valve 3, heat to 80°C and then close, open the feed valve Air valve 8 is connected to steam for heating and sterilization, with a pressure of 0.095mpa and lasting for 30 minutes. Open the water inlet valve 6, cool down to 32°C, and insert the acetic acid bacteria from valve 1 according to the inoculation amount of 10%. Open valve 9 and water outlet valve 10, turn on the self-priming motor, adjust the air volume and flow to 1:0.1, about 2.4 cubic meters, then open valve 11, aerate and culture at 30°C, the culture temperature is 31°C, and the culture time is 22-24 hours.
Quality index: total acid (calculated as acetic acid) 1.5-1.8 g/100ml, Gram stain negative, no foreign bacteria, normal morphology.
After processing, drain the contents of the tank, use an automatic cleaning device as soon as possible, and rinse with warm water for next use. Always pay attention to the working condition of the entire equipment. It is strictly forbidden to start the motor without adding cooling water to the sealing ring to avoid damaging the sealing ring. The reducer must be refueled regularly.
Scrub the tank frequently to keep the surface clean and bright, so as to achieve the purpose of durability.
