Why Farmstead Processors Choose Batch Vats

Engineered to eliminate scorching while providing total freedom for multi-product recipes.

100%

Indirect Water-Bath Heating

Thermal energy is transferred gently through a surrounding hot water jacket, eliminating direct surface hot spots and preventing milk protein burn-on.

Multi

Product Versatility

Pasteurize fluid milk in the morning, inoculate yogurt cultures in the afternoon, or process cheese curds without complex line changeover routines.

Plug & Play

Self-Contained Heating

Built-in submerged electric heating elements eliminate the requirement for expensive standalone steam boilers on small and medium capacities.

Total Cost of Ownership (TCO) & Planning Guide

A batch pasteurization vat is a key revenue driver for value-added dairy products. Evaluate operational factors before procuring.

1. CapEx Savings: Self-Contained Heating Infrastructure

For small-to-medium farmstead dairies, installing an industrial steam boiler, pressure piping, and water treatment system can exceed the cost of the pasteurizer itself.

NexAgri compact batch vats feature submerged electrical heating elements directly inside the water jacket. You simply connect municipal power (220V or 380V) and fill the jacket with water, saving thousands of dollars in initial facility utility engineering.

2. Rapid Product Changeover & Sanitation

Continuous flow HTST systems require large product volumes and continuous CIP loops. Batch pasteurizers allow processors to run multiple distinct product recipes in a single day—such as whole milk, flavored yogurt, or heavy cream—with rapid manual or spray-wand rinses between batches.

3. Value-Add Margin Impact

Selling raw fluid milk leaves farm owners vulnerable to wholesale milk price drops. Converting raw milk into pasteurized bottled milk, artisanal Greek yogurt, or farmstead cheese can significantly improve product value and retail margins through value-added processing, allowing small herds to achieve sustainable profitability.

Technical Frequently Asked Questions

Expert technical answers to help you plan your artisan processing facility.

Can I use this machine to make both yogurt and cheese in the same vat?
Yes, absolutely. Multi-product versatility is the primary benefit of a batch vat. You can heat the milk to pasteurization temperature, circulate tap water or chilled water through the jacket to drop the temperature to 42°C, add your bacterial cultures, and rely on the digital thermostat to maintain exact incubation temperatures for yogurt fermentation or cheese renneting.
Do I need an external steam boiler to operate this pasteurizer?
No, standard commercial units (30L to 150L) feature self-contained electric heating elements installed directly inside the lower water jacket. You simply connect the unit to power and fill the jacket with water. Larger industrial vats (500L+) can be configured with either high-power electrical elements or external steam connection ports depending on your plant infrastructure.
How does the cooling process work after pasteurization heating is complete?
Once the holding time finishes, you connect municipal tap water or chilled ice-bank water to the jacket inlet port. Cold water flows through the jacket, displacing hot water and rapidly lowering product temperature inside the vessel while the top agitator maintains constant product circulation.
Is 220V Single-Phase electrical power available for small facilities?
Yes. Compact units from 30L to 150L can be custom-wired for either 220V Single-Phase or 380V Three-Phase power, making them perfectly suitable for small retail shops, farmsteads, or laboratories without industrial 3-phase grid infrastructure.
How do you prevent bacteria buildup inside the vat?
All product-contact surfaces utilize mirror-polished AISI 304/316L stainless steel (Ra ≤ 0.4μm) with seamless arc transitions that eliminate sharp corners or weld crevices where bacteria could harbor. Larger units integrate rotary CIP spray balls for automated inline washing.
How do you handle overseas delivery and installation for processing vats?
Our vats are shipped pre-assembled in reinforced export wooden cases. For compact self-contained units, installation requires simple plug-and-play wiring and hose connection. For multi-vat commercial installations, NexAgri dispatches senior engineers directly to your plant to supervise piping, electrical integration, and CIP validation.
