Components of a laboratory gummy candy casting machine
In a laboratory setting, gummy candy depositing machines need to meet the research and development needs of small batches, high precision, and flexible formulations, while also considering ease of operation and convenient cleaning and maintenance. The following are key points and recommendations for selecting a laboratory gummy candy depositing machine:
1. Core Needs Analysis
Small-batch production: Single batch pouring volume is typically 0.5-10kg, supporting micro-scale testing (e.g., 50g small-scale trials).
Multi-formula compatibility: Must be adaptable to different colloids (gelatin, pectin, starch, etc.), syrup viscosity, and additives (acids, flavors, colors).
Precise temperature control: Syrup temperature control range is recommended to be 60-110℃ (depending on the formula), with a temperature difference of ≤±1℃.
Sterile environment: Laboratory-grade equipment should be easy to disinfect, and the materials should comply with GMP or FDA standards.
2. Key Equipment Parameters
(1) Depositing System
Nozzle type:
Single-head/multi-head nozzles: Laboratories typically choose 1-4 heads; multi-head systems allow for simultaneous testing of different formulations.
Needle valve control: Prevents dripping and provides higher accuracy (error ±0.5g/mold).
Flow rate adjustment: Achieved through a precision pump (such as a gear pump or peristaltic pump), adjustable from 0.1-50ml/s.
Mold compatibility: Supports silicone, metal, or 3D printed molds, with quick mold change (quick-release design).
(2) Temperature Control System
Double-layered insulated hopper: Prevents syrup from cooling and solidifying, maintaining a constant temperature.
PID temperature control module: Digital display, programmable multi-stage heating (e.g., dissolution → insulation → pouring). (3) Level of Automation
Manual/Semi-automatic: Suitable for R&D and debugging (manual control of dispensing time and speed).
Fully automatic programming: Can store recipe parameters (temperature, dispensing volume, speed), suitable for repetitive experiments.
3. Materials and Safety
Food-grade contact materials: Hopper, pipes, and nozzles are made of 316 stainless steel or PTFE (acid and alkali resistant, high temperature resistant).
Anti-scald design: Heat-insulating casing, emergency stop button.
Easy cleaning: Detachable structure, no dead corners, supports CIP (Clean-in-Place).
