Caustak 30 - 30kg

Caustak 30 - 30kg

Caustak 30 contains Caustic Soda (NaOH) and phosphorous-free sequestering agents to inhibit scale formation and improve detergency. Caustak 30 is formulated to be low foaming, enabling it to be used in recirculation applications. It is designed primarily for applications in breweries, beverage, dairy, and food processing plants. Caustak 30 is also suitable for use in other high-care industries. Caustak 30 has a high freezing point (approximately 5°C), so it must be protected from frost and wind chill during cold periods. Bulk tank systems must have trace heating, and pipework should be lagged and trace heated.

USE INSTRUCTIONS

• In-use concentrations of Caustak 30 are application-dependent and should be established during trials. A 1% v/v solution gives approximately 0.4% w/v causticity (0.4% w/v NaOH).
• Cleaning temperatures should be optimised during trials. Temperature above 90°C can be used for fatty or heavily carbonised soils. However, it is often more effective for protein soils to clean at lower temperatures (up to 70°C).
• Caustak 30 is not suitable for direct food contact.
  

The following are typical example applications. Users should refer to Cleaning Instruction Cards for specific guidance. Other applications should be discussed with your Holchem Consultant.

CIP. Caustak 30 is typically circulated for 20 – 30 minutes for Clean In Place applications at 2% to 4% v/v. The exact concentration is dependent on water hardness and soil type/level. Before circulating the detergent, pre-rinsing with water is advisable. After cleaning, the circulation loop should be flushed with clean water until the pH or conductivity of the rinsings is approximately equal to that of the water. Occasionally, CIP cleans need to be boosted with additives such as Adhol No.10. Caustak 30 is compatible with Adhol No.10, but your Holchem consultant should provide advice on procedures.

Cooking Vessel Boil-out. Caustak 30 is suitable for boil-out cleaning of cooking vessels. Depending on the level of soiling, Caustak 30 should be dosed between 1% and 4% v/v. Typical contact time (boil-out time) should be approximately 20 – 30 minutes. Where soil has become heavily mineralised (typically after repeated cooking of high dairy-content products), it may be necessary to occasionally follow a Caustak 30 with an acid clean—Nipac, Holphos, or Scalit are convenient products.
Nopac Acid can be used if a Phosphate free acid is required. Acids should not be directly mixed with Caustak 30.

Fryer Boil Out. Caustak 30 is used to boil out oil fryers to remove the carbonised oil and product residues. Typical use strengths are 2% to 4% v/v. The fryer is typically boiled for 1 to 2 hours with the detergent.

Soak Applications. Caustak 30 is suitable for soak baths used for stainless steel items at strengths up to 4% v/v. Contact time should be 30 minutes, followed by rinsing with fresh water.
