Perten Falling Number 1400

Description

Overview

The Perten Falling Number 1400 is a compact, semi-automatic instrument designed for accurate determination of sprout damage in wheat, rye, and barley by measuring the alpha-amylase enzyme activity in grains and flour. It provides reliable, reproducible results essential for grain classification, quality assessment, and compliance with international standards.

Key Features & Technical Specifications

1. Measurement Principle

• Operates on the standardized Falling Number method.
• Measures the viscosity of a heated flour-water suspension.
• Higher alpha-amylase activity (sprout damage) results in lower viscosity and a shorter falling time.

2. Technical Specifications

• Measurement Range: 60–400 seconds
• Accuracy: ±0.5 seconds
• Sample Size: 7 g of flour or ground grain
• Heating Block Temperature: 100°C (± 0.5°C)
• Timer Resolution: 0.1 seconds
• Display: Digital LCD with clear readout
• Power Requirements: 230 V AC, 50/60 Hz (models available for other voltages)
• Dimensions: 260 mm × 320 mm × 360 mm (W × H × D)
• Weight: Approx. 8 kg

3. Operation
Semi-automatic: Manual sample introduction with automatic stirring, timing, and result display.

User-Friendly: Simple three-step process:

• Fill viscometer tube with sample.
• Insert into heating block.
• Start measurement—instrument does the rest.
• Quick Results: Typical test time is 5–7 minutes per sample.

4. Standards & ComplianceICC Standard No. 107/1

AACC Method 56-81.03
