In laboratories and industrial production,freeze dryerThe vacuum freeze dryer is the core equipment for achieving low-temperature dehydration of materials and retaining active ingredients, and the Beijing Sihuan freeze dryer has become the preferred choice for many scenarios due to its stable performance and diverse specifications. This article will break down the models from the perspective of selection specifications and adapt them to the corresponding scenarios, helping you quickly select suitable equipment.
1、 Core selection specifications for Beijing Sihuan freeze-drying machine
1. Freeze dried area
The freeze-drying area is the core parameter that determines the processing capacity of the equipment. The Beijing Sihuan freeze-drying machine covers a full range of specifications from laboratory trials to industrial mass production:
0.1~0.5 ㎡: Small desktop models, such as the LGJ-10 series, are suitable for laboratory research and development of small sample sizes and small-scale trial production, with a single processing capacity ranging from a few grams to tens of grams.
1-5 ㎡: Medium sized vertical models, such as the LGJ-30 and LGJ-50 series, are suitable for pilot workshops or small production lines and can handle materials ranging from 100g to kg.
10-50 square meters and above: Large industrial models, such as the LGJ-100 and LGJ-200 series, are designed for large-scale production and can handle tens or even hundreds of kilograms of materials at a time, meeting the mass production needs of pharmaceutical companies and food processing plants.
2. Cold trap temperature
The temperature of the cold trap directly affects the water vapor capture efficiency and freeze-drying efficiency. The Beijing Fourth Ring Road models are mainly divided into three categories:
-45 ℃: Basic model, suitable for ordinary materials with low moisture content and easy freeze-drying, such as conventional food and non heat sensitive chemical raw materials.
-60 ℃: mainstream universal version, suitable for most biological products and pharmaceutical intermediates, can quickly capture water vapor and shorten the freeze-drying cycle.
-80 ℃: High end models, designed for highly heat sensitive materials such as vaccines, antibodies, and active enzyme preparations, can retain material activity to the maximum extent in ultra-low temperature environments.
3. 真空度
The vacuum degree range of Beijing Sihuan freeze-drying machine is generally between 1-30Pa, with laboratory models maintaining a stable vacuum degree of 1-10Pa and industrial models adjustable to 5-30Pa according to mass production needs. High vacuum degree can reduce the eutectic point temperature of materials, avoid material melting during the freeze-drying process, and ensure freeze-drying quality.
4. Control system
Manual/semi-automatic control: an entry-level laboratory model suitable for small batch experiments in the research and development stage, with manual adjustment of freeze-drying parameters and flexible operation.
Fully automatic PLC control: standard for medium and large models, supporting preset freeze-drying curves, real-time data recording and export, meeting the standardization requirements of pharmaceutical production and large-scale food processing under GMP standards.
2、 Applicable scenarios for different specifications of models
1. 0.1~0.5 ㎡ (-45 ℃/-60 ℃, manually controlled)
Applicable scenarios: Formula development in university laboratories and research institutes, such as exploring freeze-drying processes for new probiotic preparations and plant extracts; Small batch customized product production for small businesses, such as pet health product samples and experimental standard products.
2. 1-5 ㎡ (-60 ℃, semi-automatic/fully automatic control)
Applicable scenarios: pilot production of biopharmaceutical companies, such as freeze-drying of vaccine semi-finished products in clinical stages; The production of characteristic products in food processing plants, such as freeze-dried fruits and vegetables, and freeze-dried coffee powder, in medium to large quantities; Freeze dry virus samples from the Centers for Disease Control and Prevention before storage.
3. 10-50 square meters and above (-60 ℃/-80 ℃, fully automatic PLC control)
Applicable scenarios: Commercial vaccine and biopharmaceutical production by large pharmaceutical companies must comply with GMP certified standardized production lines; The large-scale freeze-dried food processing of food enterprises, such as freeze-dried instant noodle ingredients and freeze-dried health products; Freeze dry and store plasma components from blood stations.
3、 Key considerations for selection
Priority matching of material characteristics: Thermally sensitive materials must be selected for -80 ℃ cold trap models, while ordinary materials can be selected for -45 ℃/-60 ℃ models to reduce costs.
Combining production capacity requirements: Select small-sized models during the research and development stage, and directly match industrial models with corresponding production capacity during the mass production stage to avoid secondary equipment replacement.
Pay attention to compliance: Pharmaceutical production needs to choose models with fully automatic control and data traceability functions to meet industry regulatory requirements.
