Ultrasonic cleaning is a technology widely used in various industries, including the food industry, for efficient and effective cleaning of equipment and surfaces. It utilizes high-frequency sound waves to generate microscopic bubbles in a liquid cleaning solution. These bubbles collapse rapidly near the surfaces to be cleaned, creating a scrubbing action called cavitation, which helps remove dirt, grease, bacteria, and other contaminants.
In the food industry, ultrasonic cleaning is employed for various applications such as cleaning food processing equipment, utensils, containers, and even fruits and vegetables.
Key benefits of ultrasonic cleaning in the food industry:
- Thorough Cleaning: Ultrasonic cleaners can reach and clean areas that are difficult to access manually, ensuring a more thorough cleaning process. The tiny bubbles created by ultrasonic waves can penetrate cracks, crevices, and intricate parts of equipment, removing stubborn residues and contaminants effectively.
- Time and Cost Savings: Ultrasonic cleaning is generally faster than traditional cleaning methods, reducing the downtime required for equipment maintenance. It can also save costs by reducing the need for manual labor and expensive chemical cleaning agents.
- Enhanced Food Safety: Effective cleaning is essential to maintain high food safety standards. Ultrasonic cleaning can help eliminate bacteria, molds, yeast, and other microorganisms that can contaminate food. By ensuring a hygienic environment, the risk of foodborne illnesses and cross-contamination can be minimized.
- Gentle Cleaning: Despite its powerful cleaning capabilities, ultrasonic cleaning is gentle on the surfaces being cleaned. It can remove contaminants without causing damage to delicate parts of equipment or altering the quality of food products.
- Environmentally Friendly: Ultrasonic cleaning typically requires less water and chemicals compared to traditional cleaning methods, making it a more environmentally friendly option. It can help reduce water consumption and minimize the release of potentially harmful chemicals into the environment.
While ultrasonic cleaning offers several advantages, it’s important to note that it may not be suitable for all food industry applications. Certain factors, such as the type of equipment, material compatibility, and the nature of contaminants, should be considered before implementing ultrasonic cleaning. It’s recommended to consult with experts or manufacturers who specialize in ultrasonic cleaning systems for specific food industry requirements.
Overall, ultrasonic cleaning can play a valuable role in maintaining cleanliness, hygiene, and food safety in the food industry, contributing to the production of high-quality and safe food products.
Sediment and filtered particles of grease and frying residues reduce the permeability of exhaust air filters and metal screens, so regular cleaning is necessary. After intensive ultrasonic cleaning, the filters regain their original efficiency.
We offer a complete solution specifically for cleaning the filters and metal screens of cookers – cleaning with high-performance ultrasound. The grease filters are placed in an ultrasonic bath for a few minutes at 50-60 °C, and the dirt lines are gently removed with a biodegradable cleaning concentrate. The ultrasound creates microscopically small bubbles which, when imploded, gently remove dirt even from hard-to-reach places. The cleaned filters work reliably again after rinsing, drying and installation. This gentle cleaning method significantly extends the service life, saving time and costs. Ultrasonic baths of different sizes are available for large cleaning volumes.
How ultrasonic cleaning works?
Ultrasonic cleaning by cavitation might sound like a complicated or even scientific method of cleaning. But let us assure you, once you understand the process of it, it is actually pretty simple.
Ultrasonic cleaning is a fast and effective cleaning method which uses ultrasound energy and with the help of additional cleaning concentrates penetrates deep into the pores of any subject.
It provides thorough removal of unwanted soils from the items undergoing ultrasonic waves penetration. This cleaning method is one of the most recent and efficient ways of dirt removal from different kinds of objects. Ultrasonic cleaning method is based on a cavitation effect.
Cavitation
Cavitation is a process of fast formation and dissipation of micro bubbles in a liquid environment. The effect takes place when the ultrasonic waves are passing through the liquid. Ultrasound (high frequency sound, most commonly used from 28 to 100 kHz) generates the alternating high and low pressure waves which produce tiny bubbles (cavities). They start growing from microscopic size at the low pressure phase until they compress and then implode at the high pressure phase.
The molecules in the liquid collide releasing a massive amount of energy. The energy instantly increases the local temperature producing a high-energy stream aimed at the surface of the object. The bubbles have enormous energy which is targeted and its release lifts contamination off the surface of the objects you are cleaning.
CAVITATION PROCESS IS THE BASIS OF ULTRASONIC CLEANING.
Emission of ultrasound waves through liquid causes cavitation – formation of microscopic bubbles in liquid. When these bubbles hit the object surface they implode releasing energy that separates impurities from objects surface. Small size of bubbles enables them to penetrate cracks, holes, pores, perforations and undulations that are hard to reach when cleaning manually. Cavitation removes debris such as dust, dirt, oil, pigment, rust, grease, algae, fungi, bacteria, lime, soot, wax and so on. Materials suitable for cleaning in ultrasonic cleaner are metal, plastic, glass, ceramic and rubber. For optimal cleaning results we recommend solution of distilled water and specially formulated ultrasonic cleaning concentrates.
USE OF ULTRASONIC CLEANER IS EXTREMELY SIMPLE.
Put items for cleaning in supplied basket. Carefully place the basket with items in ultrasonic cleaner. Fill the tank with distilled water or cleaning concentrate solution. Submerge all items in cleaning solution. Set the desired cleaning temperature and activate the tank heater. When liquid in tank reaches the set temperature, the heater will turn off. Set ultrasound timer in accordance with requirements of the cleaning process, depending on the type and degree of soiling on the cleaning item. Once cleaning is complete, wait for liquid to cool down and then carefully remove basket with items. Rinse items with clean water. Drain soiled cleaning liquid from ultrasonic cleaner. Use a soft cloth to wipe the tank.
Cleaning concentrates
ASonic ultrasonic cleaning concentrates have specialized chemical composition which boosts the cleaning process and need to be used according to the special needs of the parts to be cleaned.
ASonic ultrasonic cleaning concentrates are designed not only for professional/industrial use, but hobbyist use as well.
| Cleaner | Type of impurity | Cleaning material | Dilution % | Recommended temp. |
| AS-MLP | Oil, grease, dust, general impurities | Metals, alloys, plastics, rubber, ceramic or glass components | 2% | 40-60°C |
| AS-GEN | Oil, grease, dust, general impurities | Metals, alloys, plastics, rubber, ceramic or glass components | 5% | 40-60°C |
