What Equipment Is Needed for Oral Liquid Filling Production Line?

What Equipment Is Required for an Oral Liquid Filling Production Line? The complete production process of oral liquids can generally be divided into three main stages.

Stage 1: Oral Liquid Preparation
The first stage involves the preparation of the oral liquid, including formulation, extraction, and refining. In short, this stage focuses on the production of the liquid material itself.

Stage 2: Filling and Sealing
The second stage covers the core filling process, including liquid filling, cap feeding, sealing, and transferring products to the next processing step.

Stage 3: Downstream Packaging
The third stage includes downstream operations such as labeling, coding or inkjet printing, post-sterilization, cartoning, case packing, and palletizing.

In this article, we focus on Stage 2 and Stage 3 of the oral liquid production process.

Main Functions of an Oral Liquid Filling Production Line

A complete oral liquid filling production line typically includes the following processes:
Bottle feeding → Bottle washing → Drying & sterilization → Filling → Capping & sealing → Labeling → Coding / inkjet printing → Cartoning → Case packing → Palletizing

The line is mainly composed of the following equipment:
Bottle Feeder,Vertical Ultrasonic Bottle Washing Machine, Tunnel Hot Air Circulation Sterilization Oven, Oral Liquid Filling & Capping Machine, Labeling Machine, Finished Product Sterilization Cabinet, Cartoning Machine, Case Packing Machine, Palletizing Machine.

Below is a brief introduction to each machine：

Conveyor-Type Bottle Feeder
The conveyor bottle feeder is suitable for linking glass round bottles and plastic round bottles used in syrup and oral liquid filling lines. Bottles are loaded upright in batches, and the system stores and conveys bottles automatically. Compared with rotary bottle feeders, it significantly reduces labor requirements and improves production efficiency. Only one operator is needed for easy operation.
Bottle Washing Machine
The bottle washing machine features an attractive appearance, rational layout, simple structure, easy operation, and stable performance. It is suitable for cleaning both round bottles and special-shaped bottles with shoulders. Using a two-water, one-air alternating washing process (purified water, water for injection, and clean air), it cleans the inner and outer bottle surfaces and performs preliminary drying. Bottles of similar specifications can be used interchangeably.
Infrared Tunnel Sterilization Oven
This series of far-infrared tunnel sterilization ovens is mainly used in pharmaceutical and health product industries for drying and sterilizing antibiotic vials, oral liquid bottles, and other glass containers.
Oral Liquid Filling & Capping Machine
The oral liquid filling and capping integrated machine is suitable for filling and sealing oral liquids, syrups, and medicinal liquids with different viscosities in pharmaceutical and health product industries. According to customer production requirements, machines can be customized with different capacities, such as 30 bottles/min, 60 bottles/min, or up to 200 bottles/min.
Vertical Round Bottle Labeling Machine
This machine is suitable for full or semi-circumference labeling of round bottles in pharmaceutical, food, and daily chemical industries. It can be equipped with a coding function if required.
Finished Product Sterilization Cabinet
This cabinet is mainly used for sterilizing and drying finished oral liquid products and is an essential step after quality inspection.
Oral Liquid Cartoning Machine
Designed to automatically arrange bottles (e.g., 8 bottles per tray or 10 bottles per tray), insert trays into cartons, and add instruction leaflets.
Oral Liquid Case Packing Machine
After cartoning, products can optionally be wrapped with film using a 3D wrapping machine before being packed into cartons. The system automatically packs a specified number of cartons per case based on customer requirements.
Oral Liquid Palletizing Machine
After case packing, cartons are stacked and collected automatically using a palletizing robot, ready for storage or shipment.
