JBT’s LVS QuickDry: the patented system that halves freezer drying time

jbt-lvs-quickdry-e1547743004989.jpg

JBT has launched a revolutionary new system for fast-drying of industrial spiral freezers after cleaning, helping save hours of non-productive time typically lost attempting – not always successfully – to take moisture out of freezers after defrosting.

The LVS QuickDry is an innovative solution to drying difficulties which makes use of a patented system of condensation cycles to quickly and efficiently remove all droplets of water from spiral freezers. Unlike most traditional drying systems, which rely on fans and can take an average of two-and-a-half hours to achieve results – leading to substantial downtime – the LVS QuickDry shortens effective drying time by up to an hour.

JBT’s LVS Refrigeration System is a patented invention that optimizes the refrigeration system by reducing energy consumption, improving freezer performance in the process.

“When customers have freezers, the biggest problem – as with freezers at home – is defrosting and cleaning,” explains Torbjörn Persson, JBT’s Director of Value Stream & Global Product Line, Spiral Freezers. “You can’t have a wet freezer after cleaning, so you have to dry them out and this can typically take several hours, especially with mid-sized and large spiral freezers where there’s a lot of steel. What this system does it that it shortens the drying sequence by up to one hour.”

Drying solutions
In a typical factory environment where conditions are often humid, damp and cold, drying using fans is a slow process that can leave moisture in the freezer if any attempt is made to speed it up. 

“Drying has typically been done by running fans at high speed, much like a dishwasher,” says Persson. But then, the problem is – much like a dishwasher – if you don’t open the door, it never really gets dry because it’s hard to get rid of all the moisture. And what happens is you end up with a very warm freezer that takes a long time to chill down and you still have a lot of moisture in there.”

With drying often taking up a third for total cleaning time when it comes to spiral freezers, having a dry freezer back in operation as quickly as possible is key to avoiding downtime. However, using conventional drying methods, this is not always the case.

“We know from our operational experience that a lot of customers dry and they are still not happy, so they have to dry for another half an hour before they can start running because if you have a wet freezer, water can start to freeze on moving parts causing problems with the mechanics,” says Persson. “The LVS QuickDry condensates the moisture to the evaporator before heating it again quickly using hot gas, so the moisture that has frozen to the evaporator drips down to the floor. This gets most of the moisture out of the freezer as quickly as possible.”

JBT aims to crack nut industry dilemma

JBT will be showcasing a range of solutions, including pasteurization, for the global nut industry at the upcoming Peanut & Tree Nut Processors Association (PTNPA) Convention 2019 to be held in Palm Springs, California from January 18-21, in response to the likely introduction of greater regulations for the sector. 

Following on from JBT’s successful participation at the 2018 Almond Conference, staged earlier this month in Sacramento, California, the JBT team will again seek to focus on the considerable benefits of having pasteurization in place for nut processors.

Global focus
Unlike the largely US-focused Almond Conference, the PTNPA show is expected to attract nut companies from across the globe, from peanut processors in Georgia to tree nut specialists from India. However, although the event is more international in scope, JBT’s Tricia Harlan says tree nut and peanut processors face many of the same challenges as the almond industry.

“Everything from pistachios and walnuts to cashews, peanuts and hazelnuts will be represented at the show, and these producers are likely to face the same kinds of pasteurization regulations in the future that almond producers are having to adapt to now,” she explains. 

To this end, JBT will be highlighting two pieces of equipment in particular: JBT Stein JSP-C Jet Stream® Pasteurization System Compact; and a bigger, 40 inch version of the same system for medium-large sized processors.

“This is a really important topic in general for the nut industry,” says Harlan. “Everyone is moving towards a pasteurized product, so their products are safe for consumers, and it’s very important for those processors to know that JBT has a solution for them because we’ve been validated in so many different nuts.”

JBT will be exhibiting at the Peanut & Tree Nut Processors Association (PTNPA) Convention 2019 at the Renaissance Indian Wells Resort & Spa, Palm Springs, California from January 18-21.

JBT brings full pasteurization package to Almond Conference

JBT is using the occasion of this week’s Almond Conference to launch a full service pasteurization offering – from start to finish – for the almond industry. As part of its presence at the event, which takes place in the Sacramento Convention Center, California until December 6, JBT will be offering an innovative, one-stop solution for pasteurization for almond producers and processors.

With the Almond Board of California having recently made it a requirement for almonds to be pasteurized after harvesting, there is now an obligation for farmers from California – the biggest almond production region in the US – to have pasteurization systems in place.

However, according to JBT’s Tricia Harlan, up to this stage there has not been a company willing to offer everything from a pasteurizer to a chiller to cover the entirety of the pasteurization process.

“What we are offering at the show is the pasteurizer and all ancillary equipment needed for pasteurization,” she explains. “So we’ll have conveyors, refrigeration, the steam generator, the chiller, as well as the actual pasteurizer itself, so when customers are looking to bring pasteurization from a tolling operation to in-house, they have a one-stop shop where they can get everything from us.”

Complete solution
“Most of the attendees at the Almond Conference will be from California, so in some way, shape or form, they need to have their almonds pasteurized in order to sell to the retail market,” Harlan continues. For small-medium sized processors, the complete solution will include a JBT Stein JSP-I Jet Stream® Pasteurization System Compact, alongside a JBT Frigoscandia FloFREEZE® Chiller, which is used to lower the temperature of almonds following pasteurization.

“In order to operate those pieces of equipment, you need a steam generator, refrigeration systems and conveyors, all of which will be available in our solution,” adds Harlan.

JBT’s Ramesh Gunawardena will be delivering a presentation on the almond pasteurization technologies available from JBT at the Almond Conference in Room 306–307 at 11.10 am on December 5.

JBT will also be showcasing solutions for the nut industry at the Peanut & Tree Nut Processors Association (PTNPA) Convention 2019 at the Renaissance Indian Wells Resort & Spa, Palm Springs, California from January 18-21.
