Greens Spinners for Farm Use

Download the PDF Fact Sheet Here!

Introduction

An important factor in growing and selling high-quality greens is being able to efficiently wash, cool, and dry the product. The drying step is commonly done using centrifugal force in a spinner.  The water is spun off of the greens through a filter basket or other porous container.  Some growers use mesh bags to contain the greens and improve the efficiency of loading and unloading the spinner.

Some of the key features to consider when thinking about a spinner include cost, capacity, power, space and sanitary design.

Cost

There is a broad range of spinners available and they vary considerably in cost.  Your budget may dictate which option you choose. But, consider the other features below as well. For example, a less expensive, converted washing machine spinner may actually cost more in cleaning labor when compared to a machine designed to be cleaned.

Capacity

How big is each batch or how much do you need to dry in a day?  Keep in mind that a 5-gallon spinner cannot adequately dry 5 gallons of greens since there needs to be room for the greens to spread out and not create an overly thick mat that water can’t get through. A rough rule of thumb is 1.1 gal of spinner volume for 1.0 lb of greens. Continue reading Greens Spinners for Farm Use

Produce Safety in Broccoli

Chris recently teamed up with Dr. Elizabeth Bihn of Cornell University and the Produce Safety Alliance to provide a webinar on produce safety aspects of broccoli production.  This work is part of a larger USDA SCRI project focused on Eastern Broccoli as a specialty crop with economic importance and potential in the region.

This webinar focused on the impact of the Food Safety Modernization Act and specifically the Produce Safety Rule on broccoli production in the eastern United States.

A recording of the webinar is available on YouTube and is embedded below.

Floor Design for Vegetable Wash, Pack and Storage Areas

Introduction

It is easy to ignore the thing beneath our feet, but floors are an important part of produce wash and pack areas that deserve special attention. They can impact efficiency, ergonomics, employee health, worker fatigue, personnel safety, and produce safety.  There are also a number of design features involved with these seemingly simple structures that should be considered1,2.

No two wash-pack areas are the same. Every farm has different needs driven by different crops, scales of production, layout, existing infrastructure, and management approaches.

Smaller market farms may have a very simple, open packshed design consisting of “four sticks and a lid” used primarily during the summer months. The floor of these structures could be anything: a dirt floor, grass, or gravel surface. If you choose to have a dirt floor, consider laying down weed mat or landscape fabric to create a tidy work environment. It is helpful to consider drainage, specifically providing intentional drains from wash tanks and sinks that direct outflow away from the work area, production areas and bodies of water.  The intent is to keep the surface underfoot relatively dry and free of standing water, prevent cross-contamination between drainage water and production areas and to prevent nutrient loading in bodies of water.

Larger farms and those engaged in season extension and winter markets may find benefit from an improved floor, permanent roof and walls.  When scaling up, consider the benefits of an enclosed packshed which can provide:

  • Protection from the elements as you work further into the shoulder seasons. Cooler working environment in the summer for you, your crew, the produce, and your equipment or warmer (if heated) in the fall, winter, and spring.
  • Cleaner environment for handling produce and storing containers. An enclosed space is more “cleanable” as it has doors and windows to keep dust, bugs, birds and other wildlife away from you and your produce.
This farm considered retrofitting a wash/pack room into an existing barn, but opted for the more expensive, but more flexible route of new construction.  The single-story building started with pouring a slab on grade which allowed the inclusion of trench drains. The floor is smooth, but not slippery. Note expansion joints in the floor to prevent cracking.  This building houses the wash/pack area, several coolers, break room, and a retail/CSA space.

There are several different key elements to a floor that you need to take into consideration when designing your new packshed. Continue reading Floor Design for Vegetable Wash, Pack and Storage Areas

Produce Safety Record-keeping Requirements & Tools: Presentation

This presentation discusses several different options for record keeping and tracking of produce safety documents and farm logs on an online interface. This was recorded at the Great Lakes Expo in Grand Rapids Michigan December 2017 and given by Chris Callahan UVM Extension, Ag Engineering.

Post Harvest Handling & Storage for Small Farms

This presentation was given by Chris Callahan from at the Great Lakes Expo in Grand Rapids Michigan in December 2017. He discusses the differences between fruit and vegetable storage needs, finish surfaces for wash/pack areas or coolers as well as temperature and humidity controls.

 

A frequently asked question we get is about vapor barrier usage in coolers. See Chris’ answer below addressing that question. This video shot is pulled from the above presentation and was shared on our Instagram page.

New England Vegetable & Fruit Conference 2017

In addition to attending the Great Lakes Expo, UVM Ag Engineering attended the New England Vegetable & Fruit Conference in Manchester, NH. This conference is very well suited for the small-scale and highly diversified farmers that populate the North East.

This conference is filled with a variety of vendors at the trade show, presentations covering specific details of individual crops and varieties, and even talks on designing your farm with an eye on food safety. Another interesting activity that went on was the farmer to farmer sessions that are not presentations but a lead conversation to discuss what works and what doesn’t on your farm. A lot of tips, tricks, and common complaints are all brought up and shared during this literally circled up conversation.

If you’ve never been here are a few photos from the event, which was very snowy in mid-December.

Here is a short highlight video from the conference!

 

The presentations that Chris gave at this conference can be seen below. This first one is all about designing your facilities with a food safety mindset. If you’ve never thought about your infrastructure Continue reading New England Vegetable & Fruit Conference 2017

The AZS Rinse Conveyor at Picadilly Farm


Picadilly Farm is owned and operated by Jenny and Bruce Wooster since 2006. Their farm is located in the South East Corner of New Hampshire in Winchester and has about 30 acres in production. They provide fresh produce to over 1,000 families through CSA shares spread across New Hampshire, Vermont, and Massachusetts.

Bruce reached out to share that he has an AZS Rinse conveyor and offered up his thoughts on the equipment as well.

Checking out Vendors at the Great Lakes Expo

In December, UVM Ag Engineering ventured out to Grand Rapids, MI to attend the Great Lakes Expo

This exposition was HUGE and full of a variety of seed companies, equipment suppliers, and machinery on display. There was a lot of technology targeted towards fruit growing which is big in that region which was neat to see.

Photos from the trip can be seen here.

The following are videos clips taken with vendors explaining some of what they have to offer.

Innovation in Small Scale Vegetable Washing Equipment

What’s new in Ag tech? Well, one thing that we’ve recently discovered is a rinse conveyor. Specifically designed for the small-scale farm who wants to graduate from hand washing to something a little more automated that can really crank up the pounds of washed vegetables for market.

The AZS Rinse Conveyor

This machine is made by AZS, an equipment manufacturing company in Ephrata, PA. It is available in full stainless steel, with adjustable water pressure and belt speed, available for under $7,000.
