Plate centrifuges—including the enclosed, suspended-bag, and top-discharge variants—currently represent the most mainstream and versatile equipment for solid-liquid separation across industries such as stainless steel manufacturing, chemicals, plant extraction, essential oils, fats and oils, food processing, and pharmaceuticals.

Below, I will provide you directly with the most practical and relevant information regarding application fields, process uses, and selection criteria—all specifically tailored to your business context and drawn entirely from common, real-world production scenarios. 

I. Core Application Fields 

1. Plant Extraction & Essential Oil/Hydrosol Industry (High-Frequency Usage)

Applications: Essential oil/water separation, plant residue dewatering, extract filtration, extract clarification

Scenarios:

Separation of floral/leaf residues from liquid extracts following the extraction of fresh flowers/foliage (e.g., Moringa, Rose, Jasmine, Agarwood, Frankincense)

Oil-Water Separation: Rapid separation of essential oils from hydrosols (water) following distillation and condensation

Filtration of fine fibers, impurities, and colloids from liquid extracts to enhance purity

2. Edible Oil Processing (Flaxseed, Peanut, Tea Seed, Palm Oil)

Applications: Oil residue separation, crude oil clarification, degumming, dewaxing

Scenarios:

Filtration of crude oil after pressing to remove oil cake residues and fine particles

Refining Stage: Separation of soapstock, waxes, and phospholipids

3. Chemical & Fine Chemical Industries (Wood Vinegar, Alcohol, Crystalline Materials)

Applications: Crystal dewatering, mother liquor recovery, suspension clarification, acid washing filtration

Scenarios:

Solid-liquid separation and dewatering of crystalline materials (e.g., salts, extracts)

Filtration of impurities from chemical waste liquids and suspensions

4. Food & Beverage (Fruit Juice, Honey, Starch)

Applications: Fruit juice clarification, honey impurity removal, starch dewatering, protein separation

5. Pharmaceutical & Bio-industries (Traditional Chinese Medicine Extraction, Oral Liquids)

Applications: Medicinal residue dewatering, medicinal liquid clarification, sterile filtration or applications involving essential oils, botanical extracts, or food-grade processing, the fully enclosed flat-plate centrifuge is the mandatory choice; it ensures cleanliness, minimizes material loss, and complies with environmental regulations.

II. Selection Parameters

Based on your specific business requirements, the following selection criteria are recommended:

1. Material:Full 304/316L stainless steel construction (specifically for parts in contact with the material).

2. Model: Lab/Pilot Scale:PS450, PS600

Mass Production/Production Line:PS800, PS1000, PS1250 (Most commonly used)

3. Functionality:

Essential Oils / Volatile Materials:Select the fully enclosed flat-plate model (to prevent aroma loss).

High Solids / High Residue Content: Select the flat-plate centrifuge with lifting bag discharge (for automatic bag lifting and unloading).

Viscous Materials: Select the flat-plate centrifuge with a scraper mechanism.
