Components of Laboratory Soft Candy Depositing Machine

In a laboratory environment, a gummy candy depositor must meet the R&D requirements of small batches, high precision and flexible formulations, while ensuring ease of operation and convenience in cleaning and maintenance. Below are the key points and recommendations for selecting a laboratory-scale gummy candy depositor.

1. Core Requirement Analysis

Small-batch production: The single depositing capacity is normally 0.5–10 kg, supporting micro-volume adjustment (e.g., 50 g small-scale trials).

Multi-formulation compatibility: The machine shall adapt to different colloids (gelatin, pectin, starch, etc.), syrup viscosities and additives (acids, flavors, colorants).

Precise temperature control: The recommended syrup temperature control range is 60–110 °C (subject to specific formulations), with a temperature fluctuation ≤ ±1 °C.

Aseptic environment compliance: As laboratory-grade equipment, it shall be easy to disinfect, and the materials used shall conform to GMP or FDA standards.

2. Key Equipment Parameters

(1) Depositing System

Nozzle Types

• Single/multi-head nozzles: 1–4 nozzles are typically selected for laboratory use; multi-head nozzles allow simultaneous testing of different formulations.
• Needle valve control: Prevents dripping and delivers higher precision (tolerance: ±0.5 g per mould).

Flow adjustment: Adjustable from 0.1–50 ml/s via precision pumps (e.g., gear pumps or peristaltic pumps).

Mould compatibility: Compatible with silicone, metal or 3D-printed moulds, featuring a quick-release design for fast mould change.

(2) Temperature Control System

Double-layer insulated hopper: Prevents syrup from cooling and solidifying, maintaining a constant temperature.

PID temperature control module: Digital display, programmable for multi-stage heating (e.g., sol dissolution → heat preservation → depositing).

(3) Degree of Automation

Manual/Semi-automatic mode: Suitable for R&D and debugging (manual control of filling time and speed).

Fully automatic programming: Capable of storing formulation parameters (temperature, depositing volume, speed), ideal for repeated experiments.

3. Materials and Safety

Food-grade contact materials: The hopper, pipelines and nozzles are made of 316 stainless steel or PTFE (acid and alkali resistant, high temperature resistant).

Anti-scald design: Insulated housing, emergency stop button.

Easy-cleaning design: Detachable structure, dead-angle-free design, supports CIP (Cleaning in Place).
