The Think Tank

Reconditioned Positive Displacement Pumps

Peanut butter. Jellies and jams. Salsa. Latex paints. These are thick, highly viscous products that can put your equipment under heavy load. If your company relies on positive displacement pumps to push high-viscosity products like these from one storage tank to another, you can’t afford to take unnecessary chances with flimsy equipment that isn’t up to the task. But, before you contact your Alfa-Laval, Viking or WCB dealer, have you considered the advantages of a high-quality reconditioned positive displacement pump?

Positive Displacement PumpStay with us as we explore the advantages of choosing a quality reconditioned positive displacement pump, and the multi-stage process we use to ensure customers get a product they can trust.

Strength and Reliability Under Load

Whether you need to replace a worn out positive displacement pump, or you need additional pumps to expand your production line, you obviously want high-quality equipment. But, getting a reliable positive displacement pump doesn’t have to cost your company an arm and a leg.… Read more

How to Identify a High-Quality Reconditioned Centrifugal Pump

When it comes to replacing a centrifugal pump, or adding an additional one to your existing production line, you don’t just want the cheapest possible product. You want a sanitary centrifugal pump that you can trust that maintains the high standards of your facility. After all, if your pump stops working, your product stops moving. And, if your product stops moving, you can’t fill your orders as promised.

Centrifugal PumpObviously, your pumps are not a place to cut corners. However, that doesn’t mean you necessarily need to incur the expense of a brand-new stainless steel centrifugal pump every time you want to increase production or replace a worn-out part. In this post, you’ll learn why a high-quality, used centrifugal pump could be every bit as reliable as a new pump – and for a fraction of the price.

Sometimes New Just Isn’t Good Enough

So, you’re in the market for a new pump.… Read more

Reconditioning Stainless Steel Storage Tanks, Processing Tanks & Single Shell Tanks

What is reconditioning? If you have asked this question before, you have probably gotten different answers. Here at Zwirner Equipment, we provide an extensive and diligent reconditioning process. Our reconditioning process goes beyond a new coat of paint. We also have tailored our process based on the type of equipment we are reconditioning. In this blog post, we are going to explain how we recondition storage tanks, processing tanks and single shell tanks.

Processing Tank

When you purchase a reconditioned stainless steel tank from Zwirner Equipment, it includes the following services:

1. Pressure Testing of the Heat Transfer Service: The heat transfer surface is used for heating or cooling. It is important to ensure that the pressurized jacket does not leak because leaking can cause improper heating or cooling of your product. Therefore, we conduct an initial pressure test to ensure there are no leaks in the jacket (Not applicable to Single Shell tanks).… Read more

What is HTST Pasteurization?

HTST, or high temperature short time pasteurization, has become one of the most common methods of pasteurization today. It is more frequently known as flash pasteurization, or the “continuous method”. Pasteurization destroys pathogenic organisms such as bacteria, viruses, protozoa, molds and yeasts in milk products to reduce bacterial content and deliver a safe product to the public. HTST pasteurization uses stainless steel heat exchange plates where product flows on one side while the heating media flows on the opposite side to raise milk temperatures to at least 161° F (72° C) for at least 15 seconds*, followed by rapid cooling. If the fat content of the milk product is 10% or greater, or a total solids of 18% or greater, or if it contains added sweeteners, the specified temperature shall be increased by 5°F (3°C).htst pasteurization

Why is HTST Pasteurization the Preferred Method?

High temperature short time pasteurization is a continuous process that efficiently and effectively destroys microorganisms in milk products.… Read more

What is Vat Pasteurization?

Vat pasteurization, also known as batch pasteurization or the holding method, heats every particle of milk or cream in properly designed and operated equipment, at 145°F (63°C) for 30 minutes*. If the fat content of the milk product is 10 percent or greater, or a total solids of 18% or greater, or if it contains added sweeteners, the specified temperature shall be increased by 5°F (3°C). Vat pasteurization helps destroy all disease-producing bacteria, as well as 90-99 percent of all other bacteria that may affect product quality. Because of this, pasteurization is the most important function of a milk plant.

How Does Vat Pasteurization Work?

Now that that you know what vat pasteurization is, it’s time to learn how it works. In vat pasteurization, it is necessary to heat the milk product to 145°F in the vat. The presence of both butter granules and cream plug are possible in milk and cream.… Read more
