Introduction
Modern food processing requires efficiency and uncompromising quality. Traditional spinach washing can have difficulty effectively removing fine soils, sand, small stones, and dirt particles along with lightweight
organic material like stems and small leaves without bruising the delicate leaves. Hexa Machinery has developed an innovative cleaning system specifically for spinach called the Spinach Vibrating and Air Knife
Cleaning production line solution that incorporates a mechanical vibration clean and an air knife clean approach all in one integrated system that achieves Double Cleaning. Maximum Efficiency. The proposed
Dual-Purification procedure ensures that the spinach leaves exit the cleaning system as Cleaner Spinach ready for packaging with maximum yield and minimal damage.
Primary Technology: The Efficiency of Sequence
The Hexa system's ingenuity is grounded in the sequential application of two separate cleaning forces, neither of which are destructive in nature.
Stage 1: Vibrating Screen – Delicate Shaking to Remove Heavy Impurities
Fresh spinach arrives onto the production line on a purposefully built vibrating screen bed.
The product bed is gently vibrated at a high frequency. This important action causes larger contaminants, such as infiltrated sand, small stones, and clumps of dense soil, to naturally burrow downwards within the
mass of leafy material.The amplitude and intensity of the vibration are designed to neither tear nor tumble the sensitive spinach leaves while appropriately enabling the irritation method to "Shake Off Dirt" and
transport heavy defective particles to the bottom of the product.
These larger impurities and contaminants simply fall through the screen mesh and are effectively removed from the value-added product stream.
Step 2: Precision Air Knife: Targeted Airflow for Removal of Lightly Affixed Debris
The pre-vibrated spinach then proceeds directly under one or more high-velocity air knives.
These create a powerful, laminar (smooth, non-turbulent) curtain of high speed air with precise control.
Lightweight contaminants (small stems, broken pieces of leaves, husks, insects, dust, lightweight soil, etc.) simply cannot overcome the focused air stream.
This targeted airflow will efficiently "Blow Away Debris" from the leaves that remained after vibration. Most critically, the ability to adjust the angle and air pressure allows for debris removal while the cleaned
spinach continues to pass relatively disturbance free through the air curtain zone.
The Outcome: Cleaning Spinach with a Vibrating Screen and Air Knife
This Vibrating Screen & Air Knife Combined Spinach cleaning system produces unprecedented cleaning results:
Unmatched Cleanliness: The system removes a much broader range of impurities, whether heavy (sand, stones) or light (organic debris, stems) than cleaning systems based on one method alone.
Lowest Product Damage: The system is designed for non-destructive cleaning. Gentle vibration dislodges heavy items or dirt, and precision air dislodges lighter items without relying on harsh tumbling, abrasive
brushes, or excessive water which bruise and damage to the quality of the product. By using non-destructive cleaning the integrity of the leaf is preserved, as is the texture and visual appeal.
Highest Efficiency: Extraordinary double cleaning. Maximum efficiency. Accomplishing both in one step creates less overall production time, labor requirement, and bottlenecks in comparison to multi-stage cleaning
systems that use hand and separate machine to accomplish the same results.
Maximum Discovery: The amount mechanical we reduce and damage becomes more usable product for packaging and or sale.
Repeatability: Automated and precisely controlled parameters result in the highest cleanliness and consistency be meeting parameters in each and every batch that is processed.
Safety & Hygiene: Significant microbial load and risks posed by soil and organic debris are removed by effective impurity removal. This equipment is manufactured of food-grade stainless steel [Insert if
applicable: and are ISO/CE certification compliant], making it safe and hygienic compliance with laws for food manufacture.
Applications: Quality Improvements for Everyone
This high-efficiency cleaning machine for spinach: combined vibration and air cleaning in one step is perfect for:
Fresh cut salad processors
Frozen spinach producers
Pre-washed bagged spinach lines
Organic spinach handlers who require gentle processing
Facilities focusing on high-quality leafy greens
Summary: Investment: Purer Freshness
In an industry where appearance, texture, food safety are still important, it is important to not only invest in other cleaning technology. Hexa Machinery provides: the "Dual-Purification" spinach
selector - designed to shakes off soil, blows away debris - as an improvement that processors can depend on that is more reliable, more efficient, and more gentle Shake off dirt, Blow Away Debris., to
deliver spinach that is clean to the naked eye, safer by nature, and less damaged. At the end of the day, this system delivers on its For Purer Freshness. Advanced Cleaning Tech., focuses on brand reputation,
cleaner spinach, and maximizing profits, avoids impossible issues in the work space.
