Mold biochemical incubator is a laboratory equipment specifically designed for the cultivation of molds, yeasts, and other fungi, widely used in the food industry, drug testing, environmental monitoring, and scientific research fields. Due to the strict requirements of mold growth on environmental temperature, humidity, oxygen content, and cleanliness, ordinary incubators are difficult to meet their cultivation needs. However, mold biochemical incubators provide an ideal environment for mold research by precisely controlling temperature, humidity, and air circulation. This article will provide a detailed introduction to its working principle, core functions, application scenarios, key purchasing points, and maintenance methods, helping users better understand and use this key experimental equipment.

1、 Working principle:

1. Temperature control system

-Adopting microprocessor PID control technology to ensure uniform and stable temperature inside the box (usually within the control range of 0 ℃~60 ℃, with an accuracy of ± 0.5 ℃).

-The heating method is usually electric heating wire or PTC ceramic heating, and some models are equipped with semiconductor refrigeration modules to achieve precise cooling.

2. Humidity control system

-Mold growth usually requires high humidity (70%~95% RH), and the incubator maintains humidity through ultrasonic humidifiers or water tray evaporation systems.

-The humidity sensor monitors in real-time and automatically adjusts to ensure a stable cultivation environment.

3. Air circulation system

-Built in brushless fan promotes air flow inside the box and avoids uneven local temperature and humidity.

-Some models are equipped with HEPA filters to reduce microbial contamination and are suitable for sterile cultivation.

4. Lighting control (optional)

-Some molds require specific lighting conditions (such as ultraviolet or visible light), and some incubators provide adjustable lighting modules.

2、 The main features of a mold biochemical incubator are:

1. High precision environmental control

-Small fluctuations in temperature and humidity ensure the reproducibility of the experiment.

-Support programmatic control, can set day and night temperature and humidity changes, simulate natural environment.

2. Pollution prevention design

-The inner liner is made of stainless steel material, which is corrosion-resistant and easy to clean.

-Some models are equipped with UV sterilization function to reduce cross contamination.

3. Safety protection function

-Over temperature alarm and power-off memory function to prevent accidental interruption of experiments.

-Door lock design to avoid misoperation affecting the cultivation environment.

4. Data recording and networking

-The model is equipped with USB or Wi Fi data export function for easy management of experimental data.

-Support remote monitoring, suitable for long-term cultivation experiments.

3、 Application areas of fungal biochemical incubators:

1. Food industry

-Used for detecting fungal contamination in food (such as aflatoxin detection).

-Evaluate the shelf life of food and study the growth conditions of mold.

2. Testing of drugs and cosmetics

-According to the requirements of the Chinese Pharmacopoeia and GMP, conduct microbiological limit testing on drugs.

-Test the fungal tolerance of cosmetic raw materials and finished products.

3. Environmental monitoring

-Analyze fungal communities in soil and water.

-Study the growth pattern of mold in humid environments such as basements and warehouses.

4. Research and Education

-The microbiology laboratory is used for mold isolation and purification.

-University teaching demonstration of fungal cultivation process.

4、 How to choose a mold biochemical incubator

When making a purchase, the following factors should be considered comprehensively:

1. Temperature and humidity range and accuracy

-Basic requirements: Temperature 0 ℃~50 ℃, humidity 50%~95% RH.

-High precision model: temperature fluctuation ± 0.2 ℃, humidity ± 3% RH.

2. Capacity and Load Capacity

-The common volume is 50L~500L, choose according to the sample quantity.

-Check the load-bearing capacity of the shelf (usually 5-20kg) to ensure it is compatible with the culture dish or conical flask.

3. Sterilization and cleaning functions

-Prioritize models with UV sterilization or ozone disinfection.

-Seamless welding design of the inner liner to avoid mold residue.

5、 Usage and Maintenance Guide

1. Correct operation

-Avoid frequent door opening to prevent temperature and humidity fluctuations.

-The petri dishes should be evenly placed to ensure air circulation.

2. Daily maintenance

-Clean the inner container weekly using 70% alcohol or specialized disinfectant.

-Regularly check the humidity water tank to prevent water shortage or pollution.

3. Fault handling

-Abnormal temperature and humidity: calibrate the sensor or check the sealing strip.

-Excessive noise: Clean the fan or contact after-sales service.
